An investigative report on KTLA anchor Chris Burrous has determined that his cause of death was attributed to methamphetamine toxicity, according to the Los Angeles County Coroner’s Office. Burrous, 43, was found unconscious at a motel in Glendale, Calif on December 27, and later died at the hospital. The death has been ruled as accidental.

The coroner’s report said that in addition to the Class A drug, “Other contributing factors include hypertensive and atherosclerotic cardiovascular disease.”

Glendale police were contacted by a man who told them “an individual he was with had passed out and was possibly not breathing.” The man he was with administered CPR before Burrous was taken him to the hospital. The medical emergency occurred during a sexual encounter, the Los Angeles Times reported.
