 In fact, the "supporter" from whom the murderers had borrowed their car for the killing was being paid by the New Haven Police Department to report on Panther activity, and he called his controller that night to alert the police that Sams was using his car.According to later testimony, officers followed the vehicle when it left New Haven but reported losing track of the car on its way to the murder scene.Rackley's body was discovered later that morning by 23-year-old factory worker John Mroczka, who had stopped his motorcycle near a bridge on Route 147 to check out a favorite trout-fishing spot on the river bank.
