William James McSorley, 49, was last seen standing on West Mill Street in Quakertown, Pennsylvania, on the morning of September 29, 2011, at about 8:00 a.m. Eyewitnesses report a car pulled up, pointing west toward Route 309, and McSorley, also known as Bill or Willy, got into the back seat. The vehicle drove away and McSorley has not been seen or heard from since.

At the time he disappeared he was described as a white male, five feet eight to five feet nine inches tall, weighing 230 to 250 pounds, with graying hair balding on top and blue eyes. He reportedly did not have access to his own vehicle that morning. No description of the car or driver has been publicly provided. The disappearance was not reported to Quakertown Borough Police until May 28, 2014, nearly two and a half years later; the reasons for the delay are not publicly detailed.

Very few details are available and the case remains open. If anyone remembers seeing William, the car he entered, or has other information about September 29, 2011, please come forward.
