Investigators released surveillance video from the 1800 block of Oxford Street back on March 11th.
You can see a person of interest arguing with the victim.
Moments later, a gunman runs down the street at the pair, as the first man tries to hold him back.
But he breaks free, firing at the 36-year-old victim several times. You then see a second person of interest run towards the shooting scene.
The victim died at the hospital.
If you recognize the killer or either person of interest, contact Philadelphia police.
