Philadelphia Man Arrested for Trail Slashings Linked to Infamous Cold Case Rapes and Murder

Elias Diaz, a man arrested for a series of knife attacks in Pennypack Park, Philadelphia, last month, is now the prime suspect in a 20-year-old cold case killing in Fairmount Park. DNA collected from Diaz has ties to the infamous Fairmount Park rape cases, including the death of Rebecca Park in 2003. Authorities believe he may be connected to other sexual assaults in the park. Diaz may face charges in connection with Park's death as early as Tuesday. The investigation into the cold case was aided by DNA evidence and genealogy tracing.
