A violent crime Wednesday afternoon on Interstate 5 in Federal Way has left one person dead and three injured.

At around 3 p.m. June 26, several 911 calls were made about a car in a ditch on northbound I-5 and people screaming for help.

State troopers found four people in a black BMW near the off-ramp to a Washington State Department of Transportation weigh station. One person was deceased and three were injured.

The male driver was pronounced deceased from stab wounds. A male passenger was taken to the hospital with gunshot wounds. The two in the backseat — one male one female — were taken to the hospital with stab wounds.

Police are still searching for suspects, a timeline of the event, and rationale behind the injuries.

“Obviously it is the infant stage of this investigation,” Washington State Patrol Trooper Rick Johnson told local news. “We just know everything was contained inside the vehicle. The driver is deceased from a stab wound, another individual was shot, the two others were stabbed and transported to the hospital.”

Johnson also reported that the car was a stolen vehicle, the weapon found at the scene of the crime was also stolen, and the police are looking into different avenues to solve this crime.

“We know that this is a stolen vehicle, and there is a weapon at the scene, which is also stolen. That’s what we know right now,” Johnson said. “We are trying to piece together what happened inside the vehicle. We are going to reach out to the 911 responders again and ask the public for any dashcam video that showed anything. The three surviving are detained in the hospital, and we are trying to figure out the sequence of events.”
