John Wilson, better known as rapper Tommy Hill, was talking to the manager of a bar he left without paying when he was approached by three men around 1:30 a.m. on Friday.
According to reports, one of the suspects aimed his weapon at Wilson while the others grabbed him, pushed him to the ground and began rooting through his pockets.
Wilson was later found with wounds to the chest and lower body. He was rushed to a local hospital where he died from his injuries Sunday morning, police say.
Allhiphop reports that back in 2004, Wilson cooperated with the Philadelphia District Attorney’s office in a case against a trio of North Philadelphia drug dealers accused of running a high level drug organization in which they stockpiled weapons of mass destruction.
