PHILADELPHIA (WPVI) -- There is a reward being offered in the search for a group of homicide suspects.
Police released surveillance images of the four men being sought.
Investigators say they were involved in the shooting deaths of two 18-year-old boys last June in West Philadelphia.
It happened on Arch and Vodges streets.
They were last seen in a white Nissan Maxima.
Police are offering a $20,000 reward for information that leads to an arrest.
