									                        GENERAL UNKNOWN REPORT


On 20th April 2009 @ 11.48 hrs., I came into the forensics lab and signed in for GU. Then
Ma'am divided all of us into 2 groups. I was in group-I (100). After I came to know my
group I went to Riva Ma'am to receive the evidence and chain of custody form on 20th April
2009 @ 12.00 hrs. Riva Ma'am gave me a sealed brown packet in which evidence was kept
and the sample of the evidence was SXFC-GU-113. This is how I received the evidence.


I received the evidence and chain of custody form after filling the C.O.C. form I returned it
back on the front table. My evidence # was SXFC-GU-113 and it was sealed in a brown
packet having length 11.5 cm. & breadth 11.5 cm & the height was 2 cm. The envelope ws
heavy. It was sealed from all sides, with no marks or scratches on the envelope. I have
sticked the photographs of front side and back side of the sealed envelope with frame 4 and
5 respecetively. Then I opened the packet on 21st April 2009 @ 10.16 hrs. It cut it 1.8 cm
from right side and 10.5 cm. from down. Then I took the photographs with frame # 21 for
front side and frame # 22 for back side.


Then I subpackaged my evidences I subpackaged the soil sample in an eppendorf tube and
also 2 paint chips and 2 pieces of crystals in an eppendorf tube. Then I subpacked a ring
and a black fibre in a druggist fold seperately and then a piece of stone in an eppendorf
tube and then an open golden coloured navtal lock in a brown packet by sealing it with sign
& date. This is how I subpackaged all my evidences. Refer to the photocopy for the
photographs. Then I started analyzing the evidences. Soil sample was not muddy but were
fine pieces of stones which made the soil colourful. Then the 2 paint chips were light brown
in colour. The 2 crystal pieces were of glass but not from the broken torch. The black fibre
was thick enough and is a thread through which clothes are stiched. The open lock was
golden in colour with scratches on it. After analyzing and matching the evidences with
controls I made the summary table as follows :-
                                                                            Evidential value

Reconstruction :
Ayaz Khan and attendant were crime partners. Both came early in the morning as Ayaz was
seen by chaiwalla. Then both entered inside by opening the lock but they later tampered
with the lock so that attendent would not get caught. Then they planned a bomb in the
storage room. Then later due to some argument between two of them attendant got hurt
and his green T-shirt was spoilt with blood spot and also was Ayaz's black T-shirt. But since
T-shirt was black Ayaz did not came to know about the blood spot and he asked attendant
to clean his green T-shirt so he went to bathroom for cleaning & Ayaz was still in the
storage room. As security guard saw something irregular in the storage room, he went to
call police, while in the meantime, Ayaz ran away planning the bomb with a note and taking
knapsack and map along with him he then went to bathroom and cleaned everything and
threw the map in the waste basket. Then he ran away from the station and after moving out
of the station, he threw his knapsack in the dustbin outside the station. This is the
reconstruction of the crime scene held on 18th April 2009.


Evidence SXFC-GU-113 speaks much about evidential value. It has scratches which shows
that lock is purposely tampered with screwdriver. The most important vale of lock is that it
had finger prints on it which does not matches with Ayaz Khan. Hence the golden lock
helped out in the overall reconstruction.
