A man has been charged in connection with the death of a Philadelphia real estate developer.

Michael White, 20, turned himself in around 7:30 p.m. Friday. The peaceful surrender took place at the Gospel Tabernacle Church.

Police say an altercation happened just before 11 p.m. Thursday on a downtown street, a block from Rittenhouse Square. Officers found 37-year-old Sean Schellenger lying in the road, bleeding heavily from a stab wound to the back. He died at Jefferson Hospital hospital shortly after.

Police say Schellenger and two others exited the vehicle because another car was blocking the road when the bicyclist arrived and an altercation erupted.

Police say White pulled a large knife from a backpack and stabbed Schellenger once in the back. He then fled on foot.

Police are looking into whether the man was a delivery person, as a food-warming bag was left near the bike.
