     Math Murder Mystery Teacher Overview
Unit Description
After being introduced to the mystery, students working in teams will complete seven Forensic Tasks in
order to determine time of death, develop theories of opportunity, and compile a toxicology report. Based
on their findings, students will compose a Crime Report to summarize their work and solve the murder by
identifying the perpetrator and the substance with which the victim was poisoned. After this, students will
be provided with the story epilogue to confirm their findings. Each Forensic Task must be completed and
approved by the Chief of Police (teacher) before the next task is assigned. Teams will maintain a case file
containing all of their work throughout the case.
Means, motive, and opportunity are the three aspects of a crime that are needed to convince a jury of guilt
in a criminal proceeding. The math activities in this unit deal primarily with means and opportunity and so
students are allowed to submit one question per Forensic Task to the Chief of Police in order to establish
motive. Questions such as, “How would you describe Ryan’s relationship with his grandfather?” and
“Would Anna Nicole get his fortune if Buxton died?” are appropriate.

Mystery Synopsis
Billionaire Gregory Buxton was found dead in his bed
on January 1, 2011 by his butler, Jeffrey Snow. Once
police and the forensic team arrived to the scene, it
became evident that Mr. Buxton was poisoned,
and one or some of these substances are
considered to be the murder weapon: Insulin,
Lunesta, and Levatol. Three suspects are
identified, and they are Jeffrey Snow, the
butler, Anna Nicole Buxton, Gregory’s young
wife, and Ryan Buxton, Gregory’s grandson
who is visiting from out of town.

  Mystery Introduction
Objective: Students will be introduced to the mystery and the procedures that will be followed throughout all
Forensic Tasks. Students will produce working definitions of the terms means, motive, and opportunity. Students will
the information gleaned from the Incident Statement Report to construct a graph with which they will determine the
time at which the billionaire died.

Materials Needed:

       Case file folders (one per team)
       Small ruled legal pad (one per student)
       Article, New Year Tragedy! Local Billionaire Found Dead – Poisoned?
       Crime Solving Checklist
       Establishing Motive
       Incident Statement Report
       Forensic Task 1: Determine Time of Death

Lesson Description: In this lesson, students will be introduced to the mystery and the information available to them
to solve the murder. They will become acquainted with the terms means, motive, and opportunity, which are the
three aspects of a crime that are needed to convince a jury of guilt in a criminal proceeding. Students will also learn
how to use the Crime Solving Checklist and Establishing Motive worksheets because they will be used throughout the
unit. Students will then begin their first forensic task, in which they will write and graph a linear equation to establish
time of death.

Background Information: Before beginning this lesson, students should be familiar with writing and graphing a linear
equation. Students should have a clear concept of a linear relationship. CMP2 connection: Moving Straight Ahead
1.4.

Lesson Steps: When students enter the classroom, have the terms means, motive, and opportunity written in large
letters on the board. Have their small ruled legal pads passed out to pique curiosity. Once students are settled, lead
them in a short discussion in which they first define the three terms in their own words, and then present to them
the actual definitions if they are a bit off. Explain that today they will be beginning a unit in which they will be
establishing means, motive, and opportunity in order to solve a murder, and that they will be using math all along the
way! Let students know that once they get past these initial procedural steps, work will be much more independent.

    1. As the teacher sees fit, break students into teams of three. These teams will stay the same throughout the
       entire unit. Explain to students that they will be acting as both detectives and forensics specialists, working
       with evidence and police documents to solve a series of Forensic Tasks. For this unit, the teacher will act as
       the Chief of Police, and will oversee the work of all teams.
    2. Distribute the Crime Solving Checklist (one per team). Just as the directions say, each task must be dated and
       initialed by the Chief of Police before a team may continue to the next task.
    3. Distribute the Establishing Motive sheet (one per team). Students should read directions at the top of the
       page. Explain to students that they are allowed to submit seven questions to the Chief of Police regarding the
       possible motives of the suspects. Give a couple examples of appropriate and inappropriate questions. (“Did
       the butler do it?” is an inappropriate question.)

                                                                                                                    Page 3
4. Pause for questions or clarifications. It is in steps 1-3 that the foundation, or the rules, of the unit are
   presented, so make certain that students understand the function of these first two documents.
5. Distribute the case file folders containing the article, New Year Tragedy! Local Billionaire Found Dead –
   Poisoned? Encourage students to make note of important points in their legal pads as the teacher reads the
   article aloud.
6. Distribute the Incident Statement Report and allow at least ten minutes for teams to familiarize themselves
   with the information and take notes as necessary.
7. Distribute Forensic Task 1: Determine Time of Death. Allow teams the remainder of the class period to
   accomplish the task. The teacher should circulate the room and answer any questions that arise. Students
   will also be assessed on how well they work as a team, so the teacher should make notes of teamwork
   efforts.
8. At the end of each session spent working on this unit, the teacher should collect all case files and unit
   materials.

Crime Solving Checklist
Team Members:



In order to solve this crime, you must complete each item on the checklist. Each task must be dated and
initialed by the Chief of Police before you may begin the next task. This sheet must be completed and
submitted with your Crime Report.

                              Task                                          Date           Initials

Establishing Motive
A motive is the reasoning behind why a person does something. Part of building a case against a suspect is
establishing motive. Your team will be permitted to ask the Chief of Police one question about any one of
the three suspects per Forensic Task in order to establish a motive. Think carefully before you submit your
question, because you are only permitted one per Task, and if it is denied, you will have to wait until the
next Task to ask another.

INCIDENT DETAILS
Paramedics were called to the mansion of billionaire Gregory
Buxton when his butler, Jeffery Snow, discovered him
unresponsive in his bed. Buxton was declared dead at the scene
and police were called immediately. Several medications were
found near the body, including insulin, sleeping aids, and a
common blood pressure medicine that Buxton reportedly took
daily. Two small, unidentified red stains were found at the
scene, one on the carpet an one on the corner of the night
stand. A test determined that they were not blood. Buxton’s
body showed signs of an overdose of some kind, and police are
unsure what substance might have killed him. Police suspect
foul play and the death was classified as a homicide. Crime
scene investigators determined that the body had a core
temperature of 87˚F. Police have narrowed the suspect pool
down to three individuals. Below are their descriptions.
   1. Name: Jeffrey Snow
      Age: 42
      Relationship to victim: Butler
   2. Name: Ryan Buxton
      Age: 23
      Relationship to victim: Grandson
   3. Name: Anna Nicole Buxton
      Age: 31                                                                    Page 7
      Relationship to victim: Wife
                     Forensic Task 1: Determine Time of Death
Living bodies have a constant temperature of about 98˚F. After death, they cool down by about 1˚ per hour until they
are the same temperature as the room they are in. Use the information in the Incident Report Statement to
determine the approximate time at which Mr. Buxton died. Complete the table and then write an equation to fit the
data. Display your findings using a graph that shows the relationship between time and body temperature of a
deceased person. Be sure to label the x-axis and y-axis and give your graph a title. State your findings at the bottom
of the page in a complete sentence.

MALE     Det. Allan Goss Jeffrey Snow 1/2/2011       9:36 AM
GOSS: This is Detective Allan Goss conducting interview number
one in the homicide case of Gregory Buxton. The subject of the
interview is Jeffrey Snow. Mr. Snow, can you tell me your
relationship to the victim, Gregory Buxton?
SNOW: I was Mr. Buxton’s butler for 24 years and I believe he
considered me a trusted friend. I was in charge of maintaining
all the domestic affairs of the Buxton estate, and I also
accompanied him on his travels abroad.
GOSS: I see. Are you aware of any medications that Mr. Buxton
was taking near the time of his death?
SNOW: He had high blood pressure and was taking medication for
that. Sometimes he had trouble sleeping and was trying different
remedies to address that. He was a very healthy man, other than
that.
GOSS: To your knowledge, was Mr. Buxton diabetic?
SNOW: No, he was not.
GOSS: Are you diabetic?
SNOW: What does that matter?
GOSS: Please answer the question, Mr. Snow.
SNOW: Um, no, I’m not diabetic.
GOSS: Can you tell me of your whereabouts the night Mr. Buxton
died?                                                                        Page 9
SNOW: It was New Year’s Eve, I had planned on staying in. Mr.
Buxton requested a specific type of champagne to ring in the new
year and we were out, so I made a trip to get some. I called
ahead to make sure it was in stock. I left the estate at roughly
7:15pm.
GOSS: And this store where they sell this champagne, where is it
located?
SNOW: I’d say it’s about twenty miles down the freeway. It’s
called Vincenzo’s Finest Beverages. Right off the exit,
actually. It’s the only store that carries this champagne.
Anyway, I got the champagne and returned home.
GOSS: And what time did you arrive home with the champagne?
SNOW: Oh, I don’t recall exactly. Traffic was terrible on the
way home. There was some sort of accident blocking most of the
lanes, and I was doing about fifteen to twenty miles per hour
the whole time.
GOSS: I see. And when you returned home, what did you do?
SNOW: I chilled the champagne for Mr. Buxton and went to bed.
GOSS: And the next morning, when did you realize something was
wrong?
SNOW: Mr. Buxton is, um, was, an early riser. Usually out of bed
by seven in the morning. At 8:00am he had not yet stirred and so
I went in to check on him and that’s when I…found him.
GOSS: Where was he?
SNOW: In his bed. His eyes were closed and he wasn’t moving, and
he didn’t look right so I approached him and knew right away he
wasn’t just sleeping. I called the paramedics right away and
they arrived a few minutes later but it was too late.
GOSS: Mr. Snow, did you kill Gregory Buxton?
SNOW: No! I would never do anything to hurt him!              Page 10

You have already determined the time at which Mr. Buxton died. Now you must develop, based upon the Police
Interview Transcript, whether Jeffrey Snow was home in time to commit the murder. Use the information in the
transcript to construct your response. Remember, you are not establishing guilt, you are only determining whether
Jeffrey Snow was present at the time that Gregory Buxton was poisoned.

MALE     Det. Allan Goss Ryan Buxton 1/2/2011       1:29 PM
GOSS: This is Detective Allan Goss conducting interview number
two in the homicide case of Gregory Buxton. The subject of the
interview is Ryan Buxton. Ryan, can you tell me your
relationship to the victim, Gregory Buxton?
R. BUXTON: He was my grandfather.
GOSS: Can you tell me why you were at his estate during the time
of his death?
R. BUXTON: I never saw him very much growing up, maybe a couple
times a year. He was getting older and my dad thought it was
important that I spend a little more time with him. My dad
thinks that his young wife is only into him for his money, you
know. It wasn’t my idea to spend the holiday with him; I would
have rather stayed home.
GOSS: What day did you arrive at the estate?
R. BUXTON: It was December 23rd, in the evening.
GOSS: And how long were you planning to stay?
R. BUXTON: My flight home is scheduled for January 4th.
GOSS: Ryan, you know your grandfather was a very wealthy man.
Your father is his only son and you are his only grandson. Do
you know how much money you could see in the event of his death?
R. BUXTON: Are you trying to say that I killed my grandfather
for his money?                                                             Page 12
GOSS: It’s not a bad motive, son.
R. BUXTON: I didn’t kill the old man! I wasn’t even home that
night! I was out with old friends at a restaurant. I wasn’t
going to stay out too late because my grandfather and I were
getting up early the next morning to go bird watching. Kind of
lame if you ask me, but he liked it.
GOSS: What is the name of the restaurant and what time did you
leave?
R. BUXTON: I think it was called The Westwood. Yeah, that’s it.
I remember because it’s on the corner of Santa Monica Boulevard
and Westwood Boulevard. We got through eating around 8:45pm, so
I think I was out of there by nine.
GOSS: Did you go straight back to the estate?
R. BUXTON: Yes.
GOSS: Did you take Santa Monica Boulevard home?
R. BUXTON: Yes.
GOSS: And do you know what the speed limit is on that road,
Ryan?
R. BUXTON: I don’t know, maybe forty-five miles per hour?
GOSS: That is correct. Ryan, was your grandfather diabetic?
R. BUXTON: No, but I am.
GOSS: Are you aware that there was insulin found in your
grandfather’s room where he was found dead?
R. BUXTON: I was told that, yes.
GOSS: Are you aware that the insulin was prescribed to you?
R. BUXTON: Yes.
GOSS: Ryan, did you have anything at all to do with the murder
of your grandfather?
R. BUXTON: Listen, I hardly knew the old man, and I have no
reason to want him dead!                                    Page 13

                              (Ryan Buxton)
Your next task is to determine whether Ryan Buxton was at the Buxton estate during the time of his grandfather’s
death. Police confirmed with video surveillance from The Westwood restaurant that Ryan did in fact leave the
restaurant at 9:00pm. Based upon the information in the Police Interview Transcript and the map provided, figure
out what time Ryan Buxton arrived home on New Year’s Eve after dinner with friends. Please show and explain all
calculations.

Det. Allan Goss    Anna Nicole Buxton   1/2/2011     4:19 PM
GOSS: This is Detective Allan Goss conducting interview number
three in the homicide case of Gregory Buxton. The subject of the
interview is Anna Nicole Buxton. Mrs. Buxton, please tell me
your whereabouts two nights ago.
A.N. BUXTON: How can you think I had anything to do with my
husband’s death? I shouldn’t be here, you know. Where’s my
lawyer?
GOSS: I never implied that you killed him. I simply need to know
where you were the night he died.
A.N. BUXTON: We had dinner around five. He liked to eat early. I
wanted to go out to a party for the new year but he insisted on
staying in. He said he had a trip planned with his grandson,
Ryan, and they were getting up early.
GOSS: So what did you do for the rest of the evening?
A.N. BUXTON: I called my masseuse and scheduled a massage and a
facial. And a manicure and a pedicure.
GOSS: And where were your appointments for these services?
A.N. BUXTON: Oh, when you have the kind of money we do, the
services come to you, honey.
GOSS: I see. What time were your beauty treatments?
A.N. BUXTON: I think we started at 6:15. The massage took about
a half hour and the facial about 25 minutes.                                    Page 16
GOSS: And after that?
A.N. BUXTON: I had my manicure and pedicure. I suppose that took
about an hour and a half for both. Then I went to sleep, not in
my husband’s wing of course. You see, I kept very different
hours than my husband, and he liked me to have my own space so
that I wouldn’t disturb him if I were out late. Sometimes he had
trouble sleeping and the littlest noise would wake him. I have
my own wing of the mansion-problem solved.
GOSS: That sounds like a very unconventional marriage
arrangement.
A.N. BUXTON: Mr. Goss, we had a very unconventional marriage.
GOSS: I know. Rumors certainly flew when you married him after
only a few months, and then there was that huge age difference.
A.N. BUXTON: Well, people will talk, especially in this town.
Gregory and I made no secret of our love. We were happy and
that’s all that mattered.
GOSS: How sweet. Mrs. Buxton, do you know why anyone might want
your husband dead? Did he have any enemies to your knowledge?
A.N. BUXTON: He had burned a few people as he grew his business
and fortune. The level of success that he achieved came at a
cost to someone, and unfortunately that means making an enemy
here and there. I can’t think of anyone specifically.
GOSS: How helpful of you. Mrs. Buxton, did you have anything to
do with your husband’s death?
A.N. BUXTON: Of course not! He loved me and I loved him!

             Forensic Task 4: Develop a Theory of Opportunity
                           (Anna Nicole Buxton)
Now your team must determine whether Anna Nicole Buxton had enough time to walk to her husband’s room to
commit the murder after her manicure and pedicure. You have been given a floor plan of the Buxton Estate that
shows the route that Anna Nicole could have taken to her husband’s room. Follow the directions below to guide you.

   1. Construct a simple time line of Anna Nicole’s whereabouts from dinner to the time she was finished with her
      spa treatments.



   2. With the scale on the map, use any method you choose to estimate the distance from Anna Nicole’s wing to
      Gregory Buxton’s master suite.


   3. Use masking tape to mark a length of floor that is 20 feet long. Have each member of your team walk the
      length while another team member keeps time with a stop watch. Round times to the nearest second. Keep
      your pace as natural as possible. Record the times and then find the average of the three.


                                                           4. Carry out the following conversion to determine how
                                                              many feet, on average, you walk per second.

            20ft./___        20ft./___
              sec.             sec.


                  20ft./___ sec.                               An average person walks _______ feet per second.

                                                           5. Since Anna Nicole had wet toe nail polish, police
                                                              estimate that she was traveling at a half the speed of
                                                              an average person. How fast was she traveling, in
                                                              feet per second?
                      Average
                 20 ft./_____sec.


   6. In the first question, you estimated the distance that Anna Nicole travelled from her wing to the master suite.
      Now that you have also discovered the rate at which she was travelling, determine how many minutes it took
      her to travel from her wing to the master suite.




   7. Using your timeline and your answer to question 6, is it possible that Anna Nicole Buxton could have walked
      across the estate in time to murder her husband?

MALE     Det. Allan Goss Lana Docks    1/2/2011     5:56 PM
GOSS: This is Detective Allan Goss conducting interview number
four in the homicide case of Gregory Buxton. The subject of the
interview is Lana Docks. Lana, can you tell me your relationship
to the victim, Gregory Buxton?
DOCKS: I am…was his private chef. He had a very specific diet
that he followed very closely, and he ate at the same times
every day.
GOSS: I see, and Ms. Docks, is it true that you have some
medical training?
DOCKS: Yes, I attended nursing school for a year until I found
this position. I planned on working for a while and then
returning to school.
GOSS: Is it because of the medical training that Mr. Buxton also
allowed you to oversee the administration of his daily
medications?
DOCKS: Yes, I ensured that he always had his prescriptions and
never ran out. I also set them out for him each day. He took his
blood pressure pill midday and one or two sleeping pills before
bed of course.
GOSS: One or two sleeping pills?
DOCKS: Depending on whether he felt he might need more help
falling asleep. Some days, good days, he took none at all.                  Page 23
GOSS: Is there any record of this?
DOCKS: oh yes, Mr. Buxton kept a small calendar at his bedside
at all times and marked how many sleeping pills he took. He was
a very meticulous records keeper.
GOSS: How often did you refill his prescriptions?
DOCKS: Once a month for the sleeping aid, once every two months
for the blood pressure meds. Both medicines were to be taken
once a day.
GOSS: Ms. Docks, an empty bottle of Lunesta was found near Mr.
Buxton’s body. Do you know how many pills he should have had
left in his prescription for the month?
DOCKS: I’m not certain. I would have to check his calendar.
Because it was a holiday, I had the night off and I was out with
my family. I wasn’t going to report back to work until today. It
was my understanding that Jeffrey Snow was going to take over my
duties in my absence.
GOSS: Thank you for your cooperation, Ms. Docks. You’ve been
very helpful.

                                              Epilogue
Jeffrey Snow was cleared as a suspect because he was not home at Gregory Buxton’s time of death. As a
close friend and confidant of Gregory Buxton, he was left several millions of dollars. He bought his dream
home in the Pacific Northwest and is spending his retirement hiking, fishing, and spending time with his
wife Lucinda.

It was determined that Ryan Buxton was indeed home at the time of the death, but police were unable to
produce a motive for murder. He passed a polygraph test and was cleared as a suspect. Ryan returned
home after his grandfather’s murder and has not been back to California since. He is following in his
grandfather’s footsteps, studying engineering and becoming an inventor and entrepreneur. The insulin that
was found at the scene of the crime belonged to Ryan Buxton.

The two unidentified red stains found at the scene of the crime exactly matched the color of nail polish that
Anna Nicole Buxton was wearing the night of the murder. Having had a recent manicure and pedicure, her
nails were not fully dry and the paint was easily transferred to the carpet and night stand. It was
determined that Anna Nicole Buxton was in fact home at the time her husband died. After being
questioned by detectives for five hours regarding her husband’s death, she admitted to stealing Ryan’s
insulin while he was out with friends and injecting her husband in the arm with the hormone after he had
gone to sleep. She admitted that her intent was to kill him and claim his fortune. Additionally, police
discovered that Mr. Gregory Buxton had a hefty life insurance policy of which his wife was the beneficiary.
She also stood to inherit the bulk of his fortune if she had gotten away with the crime.

Anna Nicole Buxton was tried and convicted of first degree murder for the death of her husband, Gregory
Lawrence Buxton. She is currently serving a life sentence without the possibility of parole at Valley State
Prison for Women in California.
