Two female roommates, including a former Playboy model, have been booked into jail for the murder of a psychiatrist who had been paying their rent, while the model's boyfriend remains at large.

Ex-model Kelsey Nichole Turner, 25, who is reportedly pregnant, and casino bartender Diana Nicole Pena, 30, were booked into jail in Las Vegas over the weekend for the March murder of Dr Thomas Kirk Burchard, 71.

Turner's boyfriend, 27-year-old Jon Logan Kennison, remains at large. All three are charged with murder and conspiracy to murder. 

Turner was apprehended in Stockton, California, on March 21, while she was with her child and Kennison, but he wasn't considered a suspect at the time and has since gone missing.  

Kennison and Pena were added to the homicide complaint on April 5, Las Vegas Metropolitan Police Department Det. Mitchell Dosch wrote in a redacted warrant.

Turner was extradited to Nevada on Saturday. Kennison had agreed to meet with detectives at one point, but then never returned.  

Pena was arrested on Saturday, and appeared in court on Sunday.

She is set to have a case status check on Tuesday, and both her and Turner have preliminary hearings scheduled in the case on June 3. 

Burchard's body was found rotting in the trunk of a Mercedes-Benz C300 in a desert outside of Las Vegas on March 21. 

Earp said that Burchard had signed a lease for a home in Salinas, California where Turner had lived for 'about a year' with her mother (pictured together) and children

The Clark County coroner ruled the case a homicide, finding that Burchard was struck multiple times in the head with an unidentified object that left what police called a unique pattern. 

Burchard also bore what police called defensive wounds. 

Police say the car was registered to Turner and that all three suspects' fingerprints were found inside the vehicle. A card belonging to Pena from her bartending job at Caesar's Palace was also found inside the car.

Burchard, a psychiatrist from Salinas, California, had known Turner for about two years and had given her some $300,000 over that time, the doctor's longtime girlfriend Judy Earp told The Californian. 

Earp said that Burchard had previously signed a lease for a home in Salinas where Turner had lived with her mother and children before moving to Las Vegas in 2018. 

She said the model, who appeared in Playboy Italia and Maxim, had told Burchard that she couldn't qualify for a lease because she had bad credit. 

In Las Vegas, Turner was living with her boyfriend Kennison as well as Pena and another male
