An SUV traveling at high speed slammed into a minivan at a five-point intersection in Plymouth Township late Thursday, killing three people and critically injuring a fourth, police said.

The crash, which mangled both vehicles and scattered wreckage on the roadway, occurred around 11:50 p.m. on Ridge Pike where Chemical Road and Colwell Road meet the busy thoroughfare, police said.

The names of the victims were not released.

Plymouth Township police said an officer in a patrol car witnessed the crash.

Police said the crash occurred when the driver of a Honda Pilot traveling at a high speed westbound on Ridge Pike failed to negotiate the curve approaching Chemical Road and the SUV crossed the median, slamming head-on into a Dodge Grand Caravan in the eastbound lane.

Both drivers were trapped in their vehicles and pronounced dead at the scene, as was a passenger who was thrown from the Honda, police said.

A second passenger in the Honda was taken to Temple University Hospital in critical condition.

The crash closed the intersection for about six hours.
