MINNEAPOLIS, MN. 55404
The Complainant, being duly sworn, makes complaint to the above-named Court and states that there is probable cause to believe that the
Defendant committed the following offense(s). The complainant states that the following facts establish PROBABLE CAUSE:
Your complainant is Sgt. Chris Karakostas, an investigator assigned to the Homicide Unit, Minneapolis Police
Department. In that capacity, complainant believes the facts and circumstances recited below establish probable cause:
On Thursday, June 28, 2007, at approximately 6:50 p.m., Minneapolis law enforcement responded to the scene of a
deceased female at 2435 First Avenue South, Apartment 1. Upon arrival, officers observed a Caucasian female, K.S.,
lying in the living room area of the apartment. There was blood on the floor beneath and around her body, and there
was a claw type hammer and knife near her body, both of which had blood on them. An autopsy on K.S. revealed that
she had been stabbed approximately 15 times in the neck/chest area. There was also injury blunt force trauma to her
head where she had been struck with an object. She was wearing a t-shirt and a pair of panties.
It was determined that K.S. had been living at 2435 First Avenue South, Apartment 1 with her husband, MATTHEW
LAWRENCE GRETZ (defendant herein).
A resident of an apartment adjacent to and directly south of the deceased victim’s apartment reported that around 5:00
a.m. on the morning of Wednesday, June 27 she had been awakened by yelling coming from the deceased victim’s
apartment. She heard things banging around the rooms, and at one point she heard the male party saying something to
the effect of, “Do you love me?” This resident could hear the voices pretty clearly, and they seemed to be traveling
through the different rooms of the apartment. The last thing this resident heard was two loud screams by the female
voice, then only silence.
FORM-J REV. 12/95
The Minneapolis Police Crime Lab Unit processed the apartment as well as a number of other items that they obtained
during the execution of other search warrants. These items were sent to the Minnesota Bureau of Criminal
Apprehension (BCA) for DNA testing.
Police took a statement from a taxi cab driver. He stated that he went to 2435 First Avenue South to pick up a fare. He
arrived at approximately 5:20 a.m. on June 27, 2007 and Matthew Gretz, the defendant, got into the taxi at
approximately 5:30. The defendant was driven directly to the Minneapolis Airport.
On June 30, 2007, Minneapolis police officers interviewed the defendant. He described the clothing the victim was
wearing when he left for New York on the morning of June 27. The clothing he described was consistent with the
clothing the victim was wearing when the police found her. Investigators observed an injury to defendant’s thumb. The
defendant initially denied that he had any other injuries. The police visually inspected the defendant’s body pursuant to
a search warrant. They noticed marks and abrasions on the defendant’s hands and arms, and some bruising underneath
one of his thumbnails. There was a fresh abrasion/cut on his left shin, and a number of bruises on his body, including
on his forearm, bicep, and kidney area. When T. MacDougall with the Minneapolis Crime Lab was swabbing the
defendant’s fingernails for DNA, the defendant asked if she also did manicures. Police also took the defendant’s
watch that he was wearing.
Complainant determined that the defendant had not brought his suitcase home with him when he flew back from New
York. Complainant learned that the defendant’s suitcase had been shipped to Chicago via Federal Express.
Complainant executed a search warrant in Chicago and obtained the defendant’s suitcase.
BCA determined that the watch the defendant had been wearing on June 30 had blood on the band. BCA tested this
blood and determined that it was consistent with being a mixture of DNA from two or more individuals. The victim
and the defendant can not be excluded from being possible contributors to the DNA mixture. It is estimated that
99.990% of the general population can be excluded from being contributors to this DNA mixture.
The suitcase that the defendant had taken to New York had blood on it. Three swabs of this blood was collected and
analyzed by the BCA. They determined that one swab was consistent with being a mixture of DNA from two or more
individuals. The victim and the defendant can not be excluded from being possible contributors to the DNA mixture.
It is estimated that 99.998% of the general population can be excluded from being contributors to this DNA mixture.
BCA determined that the second swab was consistent with being a mixture of DNA from two or more individuals. The
victim and the defendant can not be excluded from being possible contributors to the DNA mixture. It is estimated that
99.8% of the general population can be excluded from being contributors to this DNA mixture. BCA determined that
the third swab was consistent with being a mixture of DNA from two or more individuals. The victim and the
defendant can not be excluded from being possible contributors to the DNA mixture. It is estimated that 98% of the
general population can be excluded from being contributors to this DNA mixture.
The police obtained fingernail scrapings from the victim’s right and left hands. The Y-chromosomal DNA obtained
from these scrapings matches the Y-chromosomal DNA profile obtained from the defendant. Therefore, neither the
defendant nor any of his paternally related male relatives can be excluded as the contributor of this male DNA.
All of the above occurred in Hennepin County, Minnesota.
The defendant is presently in custody.
