PITTSBURGH (KDKA) — The jury hearing the case against 45-year-old Allen Wade got a course in DNA Analysis on Thursday.

Wade is charged with the 2014 robbery and killing of sisters Sara and Susan Wolfe. Their bodies were discovered inside the East Liberty home they shared on Chislette Street. Wade was their next door neighbor.

Dr. Mark Perlin of the Pittsburgh-based cyber genetics company that analyzes DNA evidence was on the stand most of the day.

Dr. Perlin told the jury several pieces of clothing already presented in the case were scientifically tied to Wade.

A black knit cap found near the location where Sara Wolfe car was found was 25.7 thousand time more likely a match than coincidence.

A blood stain on the pants also found near the car was 22.4 quintillion times more probably a match to Wade than coincidence.

Socks found in the same area, one of them was 300 times more likely to have belonged to Sara Wolfe.

Under cross examination, the defense tried to raise questions about the relation between the cybernetics company and the District Attorney’s office. Dr Perlin acknowledged being paid $29,000 for his work on the case.
