In a court hearing in September 2013, Prosecutors admitted to withholding from defense counsel the testimony of the only eyewitness to the murder scene, John Purvis. Purvis stated that he witnessed an Asian young man ("one of those slanty-eyed people") between the ages of 25 and 30 outside of the main entrance to Erie and a young Latin man in the building looking out of the glass at or around the time investigators estimate the murders occurred.
