These are the stories of 15 fatal chases involving Oklahoma Highway Patrol since May 2016

Stolen property or traffic infractions prompted all but one of the Oklahoma Highway Patrol vehicular pursuits that killed 18 people the past five years despite policy requiring troopers to weigh if the benefits of apprehension are worth a chase’s risks.

At least eight individuals killed weren’t the eluding drivers. Five were uninvolved motorists, at least two were passengers in fleeing vehicles, and one was a Highway Patrol lieutenant on foot struck by another trooper’s cruiser at high speed.

There could be up to two more passengers inside fleeing vehicles who were killed, but the Highway Patrol won’t say whether the deceased juveniles in two separate chases were the eluder or an occupant.
