The 35-year-old victim is the pharmacy manager at the CVS on Headhouse Square.
Just before 10:00 p.m., he was walking home.
In new surveillance video released today by police, the victim can be seen walking with his iPhone in hand on Lombard between 4th and 5th streets. Off camera, two young men, including the man depicted in the sketch, approach the victim and take his iPhone at gunpoint.
"One male had a gun and demanded the victim's cell phone. The victim complied and handed him the cell phone," Lt. Patrick Doherty of the Philadelphia Police Department said.
Surveillance then shows the victim chasing the two suspects who split up.
The victim continued to follow the suspect with the gun.
Another surveillance camera near 4th and Pine picked up the chase again.
Just off camera, the suspect turned and fired a shot.
The bullet hit the victim in the chest.
He spent the last week and a half recovering in the hospital and helped police compose a sketch of the man he remembered firing the gunshot.
"He's in good shape. He's been released from the hospital. He is doing good," Doherty said.
There was another shooting at 4th and Pine in November 2011. That case was already solved and two suspects are in federal custody.
Police are not sure if the unsolved murder of Michael Hagan in July of 2012 is related.
If you can identify the man in the sketch, you are asked to call Central Detectives at 215-686-3060.
