On the evening of April 10, 2014, a violent home invasion at the Hawkins Village housing complex in Rankin, Pennsylvania, ended with 46-year-old Lee Williams of Braddock fatally shot in the chest. Two men forced their way into an apartment shortly before 9 p.m. in what authorities believe was an attempted robbery; the confrontation left Williams dead.

Witnesses inside the home provided information that focused the investigation on 19-year-old Jake Knight. One witness recognized an intruder’s voice and later identified Knight in a photographic lineup; Knight was arrested two days after the shooting and charged with homicide, conspiracy, aggravated assault, recklessly endangering another person, and firearms violations. The second suspect has not been publicly identified by law enforcement.

In August 2016 a jury found Knight, then 21, guilty of second-degree murder, burglary, and reckless endangerment. In November 2016 he was sentenced to life in prison without parole plus an additional two and a half to five years for the other charges.

If anyone knew Lee Williams or has information about the unidentified second intruder, please share what you know.
