Dr Segal gave two examples of how forensics
can help to solve crimes:
1. A man reported his neighbour missing.
He had not seen her for two days. Police broke in and found
the woman dead. The Forensic Examiner examined the body and
the crime scene.
A post mortem found that the woman had been dead
for longer than three days. This made police immediately suspicious
of the man who reported her missing. Detectives interviewed
people and a Forensic Team checked out the woman's flat. In
the flat, they found fingerprints of the neighbour who reported
the crime. The fingerprints were in places that you would not
think a neighbour would look. This, together with evidence of
damage to the neck of the dead woman, showed "foul play".
By working backwards and trying to work out what
had happened prior to the woman dying, the police were able
to make an arrest. It was thought that the man had hoped that
by leaving it a few days, any evidence of how his neighbour
was murdered would be lost.
2. In the London bombings on July 7th 2005,
detectives worked backwards to piece information together.
Police gathered information from families regarding
missing people or victims. They contacted families and took
evidence, e.g. hair from hairbrushes to match the DNA of the
bodies and body parts found. Blood was picked up from the crime
scene by using special chemicals.
Questions from the floor:
How do you tell if a person has been murdered?
There are many ways of working out that a person
has been murdered. For example, a woman was found hanged outside
her house. The knot was in a place that it was obvious (to the
trained eye), that she could not have placed it there herself.
Therefore she had been murdered.
CCTV cameras can also help with evidence. It is
possible to zoom into the finest details (1 in 10 million) and
identify the colour of a person's eyes, and guess height and
hand size. This would be 95% correct and legally binding in
a court of law.
How can we tell criminality?
A woman falls from a bedroom window. Were the
injuries on her body in line with the height that she fell from?
If they were worse, it could indicate that she was pushed.
Sometimes cause of death is only discovered at
the post mortem, by a pathologist.
How is the post mortem affected when a Jewish
man or woman dies, because the funeral must be carried out within
48 hours?
The police are very aware of religious beliefs
and principles. A team of people tries to take as much evidence
as possible to speed up the process. Permission is needed to
do a post mortem. The only exception to this is when a post
mortem is essential for national security - in this case, permission
is not needed.
In the case of the London bombings, people came
from all over the world and relatives wanted the bodies flown
home to different countries. The police could get bomb material
from the bodies and so they needed to have access to the bodies.
The Jewish Burial Society Chevra Kadisha can get
involved.
Is there a priority regarding Jewish deaths?
Only if there is no suspicion linked with the
death. The team works as quickly as possible in all other cases.
Many thanks to Dr Segal for a very thought-provoking
talk.
