The incident took place back in November. Firefighters were called to the 3500 block of North 10th Street for reports of two vehicles on fire.
When crews put out the blaze, they discovered a body in a Jeep Cherokee.
Officials later determined the fire was set intentionally.
Police are now asking the public to help them identify a man seen in the area moments before those vehicles went up in flames.
Authorities say if you recognize the man to contact police immediately.
