CRYSTAL, Nev. — Former NBA star Lamar Odom is on life support after being found unconscious at a brothel in Nevada.
Odom had been using cocaine on Saturday, employees at the Nevada brothel where he was found unresponsive Tuesday told 911 dispatchers, Nye County Sheriff Sharon Wehrly told reporters.
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.
Khloe Kardashian will make medical decisions for former NBA star Lamar Odom, who is hospitalized in Las Vegas, a source close to Kardashian said. The couple's divorce has not been finalized, the source tells CNN. Lamar's father and two children are with him at the hospital, the source says.
The site manager of the brothel where Lamar Odom was found unresponsive told CNN that when he arrived in the room the former athlete was on his right side and wouldn't wake up when people shook him.
Richard Hunter said Odom was snoring loudly, had his eyes closed and was unresponsive, so he called 911. Hunter said two women who had been with Odom earlier handed him a bottle of a legal herbal supplement that is sold at the brothel. He said the two women saw Odom take 10 pills over three days, as well as drink alcohol.
A Nevada sheriff says the 911 caller said the former NBA star had been doing cocaine and had taken sexual performance enhancers.
Odom was found unresponsive Tuesday at the Love Ranch in Crystal, the Nye County Sheriff's Office said.
"He doesn't look good," brothel owner Dennis Hof said. "He doesn't look like he'll make it, and if he does, he won't be the same."
Officials haven't said what was wrong with Odom, and his condition remains unclear.
Authorities originally planned to fly him to a hospital, but said the 6-foot-10 Odom was too tall to fit in a helicopter. He was taken by ambulance to a hospital in Las Vegas -- about 60 miles away.
Odom, 35, won two NBA championships as a forward for the Los Angeles Lakers.
He married the younger sister of Kim Kardashian after a whirlwind romance in 2009. Khloe Kardashian filed for divorce four years later, citing irreconcilable differences.
Khloe Kardashian has been at the hospital by Odom's side since Tuesday night, according to source close to the reality star. She asked that people keep him in their thoughts and prayers and respect his privacy, the source said.
'Everything was great'
Hof said Odom called him Saturday and told him he wanted to visit the brothel for a few days. Hof let him stay at his home, which is attached to the brothel.
"He was having a good time at the ranch and everything was great," Hof said, until Sunday, when Odom seemed "a bit somber" because people were "calling and bothering him."
"Late Tuesday, two women at the brothel went to check on Odom and found him unconscious," Hof said.
"To my knowledge, there were no drugs involved. Lamar was eating well and was just healthy."
Brothels are legal in Nevada in counties with fewer than 700,000 people, according to state law.
The brothel could lose its license if any wrongdoing is found, authorities said at the press conference.
In addition to appearing on "Keeping Up With the Kardashians," Odom and Kardashian had their own reality show, "Khloe & Lamar." It lasted for two seasons and 20 episodes.
Despite going separate ways, Kardashian has said she will always love him.
"I will never, ever not love Lamar," she told E!, which airs their reality shows. "I was so obsessed with him in a healthy way. He was my husband, and I still wish he was."
Kardashian has expressed concerns for him, especially after his best friend died this year.
Despite her family's objection, she regularly talked to her ex-husband by phone during episodes of "Keeping Up With the Kardashians" this season.
Veteran NBA player
Odom played for four teams during his 14 seasons in the NBA and won the Sixth Man of the Year Award during the 2010-11 season.
He was drafted by the Los Angeles Clippers in 1999, playing for the team for four seasons before signing with the Miami Heat.
"Our thoughts and prayers are with Lamar Odom and his family at this time," Miami tweeted.
New York Knicks star Carmelo Anthony tweeted his prays for Odom Wednesday afternoon.
Fellow NBA player Dwyane Wade said he was up late, worried about his friend and former Miami teammate.
"I can't help but to be up right now ... ," he tweeted early Wednesday. "On my knees praying ... please God let him pull through."
After one season in Miami, Odom was traded to the Lakers and was a key part of their championship teams in 2009 and 2010.
A year later, he played briefly for the Dallas Mavericks before returning to the Clippers for one season. He has not played in the NBA since then.
But he has continued making headlines, including for a drunken driving charge two years ago. He pleaded no contest and received three years' probation.
