The Pennsylvania State Police and other agencies have joined the search for the third suspect in the weekend stabbing of Steelers tackle Mike Adams.

Pittsburgh police this morning released the identity of the third man they are seeking, 26-year-old Jerrell Whitlock of Hazelwood. He faces charges of attempted homicide, attempted robbery, aggravated assault and conspiracy.

The acting city police major crimes unit commander, Kevin Kraus, said at a morning press conference that police searched Hazelwood and other parts of Allegheny County last night and suspect that Mr. Whitlock might have left the area.

Two other men, Dquay Means, 26, and Michael Paranay, 25, both of Hazelwood, have already been arrested in the case.

Mr. Means, a rising rapper who appeared in the music video for Wiz Khalifa's hit song "Black and Yellow," goes by the stage name Quay Meanz and recently signed with Khalifa's fledgling music label.

Pittsburgh police wrote in a criminal complaint that Mr. Adams left Cambod-Ican Kitchen at 17th and East Carson streets shortly before 3 a.m. Saturday and three men approached him.

Mr. Adams told police that Mr. Paranay said the football player's black Ford F-150 Raptor was a nice truck, and Mr. Means said, "Gimme your car."

Mr. Adams told Mr. Means, "You aren't gonna shoot me on the street in front of people," and Mr. Means responded "I want your car or I'll shoot you in the face and kill you in front of people," according to the complaint.

Police suspect that Mr. Paranay punched Mr. Adams in the face, while Mr. Means pointed a gun at him and Mr. Whitlock stabbed the Steelers player in the abdomen, cutting so deep he sliced part of Mr. Adams' colon. Mr. Adams was released from UPMC Mercy Hospital on Tuesday.

Homicide detectives tied Mr. Paranay to the crime after he dropped a cell phone at the scene. A witness saw the cell phone and handed it over to police.

"The cell phone was the key piece of evidence in this case that directed us directly to Paranay," Cmdr. Kraus said. "We've also collected some video surveillance evidence in the area that has been very valuable to the investigation."
