CHESTER, Pa. (WPVI) --Chester County officials are joining forces with the Delaware County district attorney's office to try to catch a killer.
They announced Monday a $10,000 reward for information leading to an arrest in Chester's first murder of 2016.
It was last Friday night when a 42-year-old man was found shot to death inside a car at 15th Street and Shaw Terrace.
Law enforcement officials are telling residents they need their help.
"It's time that the police, the district attorney's office, that the residents in the city of Chester work together to make our community safer," said Delaware County District Attorney Jack Whelan.
Authorities say they believe someone knows more about the killing and hopes that the reward will increase the amount of leads.
