Solomon Burton, 25, was killed the night of Thursday, November 29, 2012, after approaching a second-floor Lawrenceville apartment that also served as a recording studio. Burton, of Mount Lebanon, reportedly knocked on the door shortly before 10 p.m. and was armed when the occupants opened it. People inside the unit, who were also armed, shut the door and fired through it. Burton was struck multiple times, including two shots to the chest, and was pronounced dead at the scene.

A gun was recovered outside the apartment door. Pittsburgh police detained four people from the studio for questioning that night and investigators said others may have left before officers arrived. No arrests were announced in the immediate aftermath and authorities were still working to determine a motive and identify everyone involved.

If anyone has information about what led to that confrontation or who else was present, please share it with investigators.
