 Dr. Henry Lee, director of the Connecticut State Forensics Science Laboratory, testified on August 23-24, 25 and 28.He stated he discovered shoe imprints near the murder scene that could not have come from the shoes the prosecution claims Simpson wore the night of the murders, suggesting a second attacker was present.Lee noted that the blood patterns suggested Goldman tried to fend off his attacker for an extended period of time, contradicting the prosecutions claim the murders only took minutes.
