Traffic investigators are still working to learn more about a two-car crash in Youngstown that sent four people to the hospital.

Police were called to the area of Hillman Street and Cohasset Drive at around 7 a.m. Friday where they found two heavily damaged cars.

A Kia and a Mercury were nearly a block from each other along Hillman.

Two ambulances were called to transport four people to the hospital for treatment of injuries police say are not life-threatening.

Both vehicles were off the road and traffic did not have to be shut down
