Lamar Odom, the two-time NBA champion and estranged husband of reality star Khloé Kardashian, has been hospitalized since Tuesday after he was found unconscious, face down in Dennis Hof's Love Ranch brothel located in Crystal, Nevada, as previously reported by HNGN. Odom has remained in critical condition in a medically induced coma since Tuesday night.

Here's everything we know so far about Odom's condition and the circumstances that led to this tragic event.

Dennis Hof's Love Ranch

Odom arrived at Dennis Hof's Love Ranch, a legal brothel located just an hour outside of Las Vegas in Crystal, Nevada, on Saturday night. Odom reportedly told ranch employees that he wanted to be left alone, and was last seen at 6 a.m. on Tuesday. He reportedly seemed "irate" on Sunday, which was the day an episode of "Keeping Up with the Kardashians" (one of the E! reality shows that he appeared on regularly with his estranged wife Khloe) aired and portrayed his reaction to his friend's death. His body was found face down in his room at the brothel at around 3 p.m. that day, and Odom was unconscious but breathing. Two separate brothel employees made two separate 911 phone calls.

911 Phone Calls

During a press conference given by the Nye County Sheriff's Office, two 911 recordings were played to a room of reporters. In those 911 calls, hostel employees stated that Odom used cocaine on Saturday before he arrived. They said Odom also took at least 10 natural male performance enhancement pills called "Reload," an herbal supplement that had been deemed "dangerous" by the FDA, which were made available to him at the ranch.  They confirmed that Odom was breathing but he had a white substance coming out of his mouth, and was bleeding from his nose and mouth when he was found.

Hospitalization

An ambulance arrived to take Odom to the Desert View Hospital (located about 20 minutes away in Pahrump, Nevada) and responders then attempted to airlift Odom in a Mercy Air helicopter, but because of his 6-foot-10-inch stature, he could not fit into the patient compartment. Odom was then transported to the Sunrise Hospital and Medical Center, where he has remained hospitalized.

Condition

Odom remains in critical condition after being placed under a medically induced coma at Sunrise hospital. Recent conflicting reports have stated that Odom has shown signs of "slight improvement," like eye movement and allegedly squeezing the hands of his estranged wife Khloé and sister-in-law Kim Kardashian-West, but Odom still remains on life support. Another report claimed Odom's condition had gotten "no better, no worse." Along with his kidneys, three other organs have started to fail him and doctors have given him a 50 percent chance at survival.

Investigation

Odom's incident at Dennis Hof's Love Ranch is part of an ongoing investigation by the Nye County Sheriff's Office, investigator Michael Eisenloffel confirmed, during a press conference. Eisenloffel and his partner arrived at Odom's room at the brothel shortly after his body was taken away in the ambulance and gathered evidence at the scene, as well as conducted interviews with brothel staff and the two women who spent time with Odom during his stay. Investigators then obtained a search warrant for Odom's blood, which was drawn at Sunrise Hospital. Odom's blood was submitted as evidence in the investigation, then taken to the Las Vegas Metropolitan Police Department Laboratory for testing. It could take several weeks for test results to come back.

Friends and Family Show Unwavering Love and Support        

When news broke of Odom's condition, Khloé flew out to Las Vegas with her sister Kim and mother Kris Jenner to be by his side. The estranged couple signed divorce papers in July, but due to a backlog in family court, they are still legally married. Because Khloé is still Odom's wife by law, she has the power of attorney. Khloé holds the difficult task of making medical decisions for Odom, and she has made several since his hospitalization.

Khloé also paid for Odom's father Joe, his daughter Destiny, son Lamar Jr., aunt JaNean and Odom's ex Liza Morales to fly out to Las Vegas to be there with Odom in the hospital. Odom's friend and former teammate Kobe Bryant, and family friend Jesse Jackson, also stopped by to show their support along with various members of the Kardashian/Jenner clan.

Kourtney and Kylie arrived at the hospital to visit their brother-in-law during this difficult time. Caitlyn Jenner is reportedly en route to Las Vegas. Kim canceled her baby shower this weekend in order to stay in Las Vegas with her family, while her husband Kanye West is in Los Angeles caring for their daughter North, and Mason, Penelope and Reign, the three children Kourtney shares with her ex-boyfriend Scott Disick.

Rob, Kylie and Kris Jenner, and many other celebrity friends and NBA stars have all shared sweet messages and tributes to Odom on social media.
