scene was contaminated when the police covered Simpsons body with a blanket, they
suggested that OJs hair had fallen out when he had laid back on the couch and the blanket
had picked it up which had then been transferred to the victims body. The defence also
argued that the investigators had picked up some of OJs hair when taking his statement and
then transferred them to the scene in accordance with the exchange principle.
Bite marks
Bite marks are most commonly found in cases of sexual assault and are linked back to the
offender based on dental records. Bite marks should be photographed so that a mold can be
made against the suspects teeth as well as the victims to see if the mark could have been
self inflicted, a special orthodontist can be consulted and used on the stand to evaluate the
possible links between the mark and the suspect.
Case Study- Ted Bundy
Ted Bundy is one of America's most infamous serial killers who was active in the mid 70s.
He was convicted of aggravated kidnapping, attempted murder, burgalry and murder. Bundy
was convicted of the murder and rape of Lisa Levy when investigators examined
photographs of a bitemark left on her body, molds were then taken of Bundy’s teeth, he had
extremely crooked lower teeth making it an easy case for prosecutors to make that the bite
mark was left by Bundy.
