PHILADELPHIA (WPVI) -- Philadelphia police are hoping someone may recognize a murder suspect.
They released a surveillance video showing the man they're looking for.
He allegedly stabbed a 22-year-old to death on Sunday, July 21 in Kensington.
The grainy footage shows the suspect leaving the area of Allegheny Avenue and E Street.
At one point, he opens a fire hydrant.
