The Pennsylvania Supreme court has upheld an earlier ruling by the State Superior Court, granting a Norristown man’s request for DNA tests on evidence from a crime committed 25 years ago. 53-year-old Robert Conway was found guilty of third degree murder in the 1986 stabbing death of Norristown shopkeeper Michele Capitano. She was 35 at the time and he was 29. She worked at the former Wooley’s Surgical Supply store on DeKalb Street. Court documents say she was stabbed 78 times in the store’s bathroom. His lawyers want the testing done on several items, including bloody paper towels that the killer presumably used to wash his hands, the victim’s clothing, and fingernail clippings from her hands. They say new technology not used in criminal trials at the time he was convicted could prove his innocence. Conway has always maintained that the victim was already dead when he arrived at the store.
