Older and younger is easier than middle age. • -do cases come around for you quite often or just every once in a while? • We see case almost every day because we draw from such a large number of agencies
Case Study: Name: Theodore Robert Bundy FBI Case No: 251163P2 Date of Birth: 11-24-46 The cause of death for Lisa Levy and Margaret Bowman was strangulation. Additionally, they received severe beatings from what was discovered to be a length of a tree branch used as a club. Margaret Bowman's skull was crushed and laid open. Lisa Levy had been bitten with sufficient intensity to leave indentations, which could clearly be identified as human bite marks. As a part of the investigation, police technicians took numerous photographs of the bite on the victim's body. A forensic odontologist then made molds of Bundy's teeth. When compared to the bite marks the molds matched perfectly. This is why forensic odontology is so important because one of the most infamous killers in America, Bundy, who was so good at leaving no evidence was caught with one piece of evidence: a bite mark.
