Law enforcement officials have released recordings of 911 calls made by employees of a Nevada brothel seeking help for former NBA player Lamar Odom, who was found unconscious and rushed to the hospital Tuesday.

During one of three calls played by the Nye County Sheriff’s Department during a press conference Wednesday, a man is heard telling a 911 dispatcher that Odom had used cocaine on Saturday, but not since then.

The caller also said Odom had used up to 10 tabs of sexual enhancement supplements over three days and that he was unconscious, but breathing. Odom had blood coming from his nose and mouth, as well as a white substance, the caller said.

Authorities obtained a search warrant to test Odom’s blood for blood for drugs, Nye County Sheriff Sharon Wehrly said during the press conference, and are awaiting toxicology results. A source told People that doctors found “cocaine and opiates” in Odom’s system and that he had suffered several strokes in the hospital.

“We would like to extend our best wishes to Mr. Odom and his family and we’re hoping for a speedy recovery,” she said.

A source told People that Odom is currently in a coma, and that family members — including estranged wife Khloé Kardashian, Kim Kardashian, and Kris Jenner — are “praying for a miracle.”
