Two people are dead after a woman stole an Ambulance at knife point and crashed into a semi truck in Frazier Park, 60 miles north of Los Angeles, California.

According to KTLA 5, the woman called 911 on Wednesday evening to report a seizure, but pulled out a knife when paramedics arrived and demanded the ambulance. Once in the ambulance, she sped off, and drove through town at approximately 100 miles-per-hour.

As she approached Interstate 5, she collided with a semi truck that was pulling into a Flying J, instantly killing herself and the truck driver.

An investigation is currently underway, some preliminary reports claim the woman may have been suicidal. Neither driver’s names have been released.
