Two people were decapitated in what police believe to have been a drunk driving accident in California on Sunday. 

The incident happened just before 1 a.m. near Mission Hills on the 5 Freeway. 

According to The Los Angles Times, 37-year-old Juan Carlos Menjivar was driving a 2010 Lexus sedan with 33-year-old Ana Elena Moreno Santos riding as a passenger southbound on the 5 Freeway near the 405 Freeway exchange when Menjivar “failed to maintain the curve in the roadway before traveling out of control” and slamming into a tractor trailer parked on the right shoulder of the highway. 

Menjivar and Santos were pronounced dead on scene due to  “major trauma to the head,” CHP spokesman Ramondo Alexander said.

“All I felt was a major hit,” said the 35-year-old truck driver. “I felt like I was hit by a semi.”

The trucker did not wish to be identified. Police say alcohol and excessive speed were likely factors in the crash. The incident is still under investigation.
