Philadelphia crime scene investigators and now a forensic expert are digging for clues in a North Philadelphia alley where a jawbone was found last week.
The Philadelphia Crime Scene Unit has set up tents and other equipment in the dirt tract behind a baseball field at 4th and Westmoreland Streets.
Police say the unit is continuing to look for clues at the site after a lower jawbone was uncovered there on Friday afternoon. The dig carried over into the weekend and again this week.
Investigators have been digging at the scene as part of a probe of former homicide detective Ron Dove, officials said. Dove is set to be fired after a standard 30-day waiting period for allegedly lying to police about helping his girlfriend, 33-year-old Erica Sanchez, after she allegedly murdered her ex-husband.
The department began reviewing several cases Dove had worked on after the revelations.
Sources tell NBC10 Dove is suspected of covering up three murders and a man's disappearance.
Detectives have been searching and digging in the same area for the past month, but had yet to find any evidence, according to sources.
An anthropologist from the University of Pennsylvania is being brought out to the scene to analyze some items investigators found at the dig site, sources say.
As for the jawbone that was found last week, officials may have a positive identification as to who it belongs to as early as tonight, according to sources.
