Corey Haim 911 Call: "He's Completely, Completely Gone"

Mother Judy Haim desperately attempts to revive her son as she tries to get paramedics to her apartment

This is every mother's worst nightmare.

Judy Haim desperately—and heroically—attempted to revive her son, Corey Haim, after he stopped breathing early in the morning on March 10.

Los Angeles authorities have released the heartbreaking recording of Judy's 911 call in which she pleads with her 38-year-old son to wake up.

"Oh my god, I think my son is dead," she declares. "Listen, he's not breathing…I don't know what's going on. He had a fever this morning and cold. Core! Core, please get up…He's completely, completely gone."

The dispatcher asks her if he's breathing—he wasn't—and instructs her to bring him from the bed to the floor before he gives a tutorial on administering CPR.

As she pressed on his chest, she explains in more detail what happened before her call.

"I am pressing, but he's not moving. He's not moving," she cries. "He all of a sudden got out of bed. He wanted to go to the bathroom and he fell on the floor and I put him on the bed and then that was it. His eyes went backwards. Oh my god. Core! What's happening?"

Sadly, we all know what happened once the ambulance arrived. The Lost Boys actor was taken to Providence Saint Joseph Medical Center in Burbank, Calif., and pronounced dead around 3 a.m.

An autopsy was conducted the following day, but the findings remain inconclusive pending toxicology test results. Drugs are widely suspected to have played a hand in the tragedy.
