Elias Diaz has been charged in the 2003 rape and murder of Rebecca Park in Philadelphia's Fairmount Park after DNA evidence allegedly linked him to the cold case. Diaz was arrested in connection with recent machete attacks and was identified through his fingerprints. Investigators believe DNA evidence and other evidence connect him to the 2003 killing. Diaz faces charges of murder, rape, aggravated indecent assault, and possession of an instrument of crime. He may also face charges in other assaults. DNA techniques advanced enough to finally identify Diaz, who has been evading justice since 2003.
