DNA Evidence Used In Hunt For Norristown Gunpoint Rapist: DA

NORRISTOWN, PA — An advanced science called DNA phenotyping is being used to help authorities hunt down the man who sexually assaulted a 19-year-old runner at gunpoint last summer, according to the Montgomery County District Attorney's Office.

Authorities are using the suspected rapist's DNA to help predict his physical appearance and create an illustration of his face.

Investigators are working closely with Parabon NanoLabs on the case, and hope that it will help provide them with a lead in the incident which occurred over the summer. A press conference providing details on this process has been scheduled for next Tuesday afternoon.

The incident occurred on Aug. 1 in Norristown Farm Park, at some point between 10:30 a.m. and 10:50 a.m., investigators said. The quiet area has miles of running and hiking trails and is not traditionally a haven for crime.

The suspect, a black male wearing a dark-colored hooded sweatshirt, and armed with a handgun, held a gun to the woman while sexually assaulting her, police said. He then fled the scene.

The victim called 911 immediately. Authorities searched the area when they arrived but could not find the suspect.

The suspect is described as a male in his 20s or early 30s with medium brown skin, standing between 5 feet, 5 inches and 5 feet, 10 inches tall. He also has an average build, police said.

West Norriton Police and the Montgomery County Detective Bureau are working together on the investigation.

A $10,000 reward has been posted for information that leads to the capture of the suspect. If you have any information, please call 610-278-3368 or 610-630-1701.
