Lamar Odom Hospitalized. What Truly Happened?

Former NBA star Lamar Odom had been using cocaine on Saturday, employees at the Nevada brothel where he was found unresponsive four days later told 911 dispatchers, Nye County Sheriff Sharon Wehrly told reporters Wednesday.

Investigators have obtained a blood sample from Odom, which will be submitted for testing to the Las Vegas Metropolitan Police laboratory.

"At this point, the case is ongoing," Wehrly said.

On a 911 call played at a news conference, a woman says she also saw Odom take 10 herbal

supplement tablets over three days.

Odom was found on Tuesday, the fourth day, lying in bed on his side, with a pinkish fluid coming from his mouth and nose, callers told 911 operators.

He was taken to a hospital in Las Vegas, about an hour's drive from Crystal.

Pahrump Valley Fire Rescue Chief Scott Lewis told reporters there were no incidents as Odom was driven from a hospital in Pahrump to Las Vegas. 

Reality television star Khloe Kardashian will make medical decisions for the former NBA star, a source close to Kardashian said Wednesday.

The couple's divorce has not been finalized, the source told CNN.

Kardashian's mother, Kris Jenner, posted a message to Instagram.

"Please pray for Lamar #ourfighter," she wrote.

He is recovering.

Odom's father and two children are with him at the hospital.
