Las Vegas authorities allege in newly-released court documents that the Playboy model accused of killing a respected California child psychiatrist was in an intimate relationship with him.
Authorities have also arrested the roommate of suspect Kelsey Turner, 25, alleging Diana Nicole Pena, 30, also participated in the March beating death of Dr. Thomas Burchard.
A third roommate, Jon Logan Kennison, who was Turner’s boyfriend, is also accused of participating in Burchard’s slaying but has not yet been apprehended.
The 71-year-old doctor’s beaten body was found March 7 in the trunk of a blue two-door 2017 Mercedes-Benz that had been left in the desert just outside Las Vegas. An autopsy determined Burchard died from blunt force trauma to the head, with the manner ruled a homicide.
An arrest warrant recently obtained by PEOPLE indicates Burchard paid the rent at the Turner’s home for the months of March, April, and June.
Turner and Burchard first met two years ago.

Burchard’s longtime girlfriend, Judy Earp, told KTNV her boyfriend was a generous, compassionate man who may have given Turner approximately $300,000 over the years.
Turner was arrested on March 21.
According to the warrant, Burchard’s blood was found throughout the inside of the vehicle, which Turner allegedly purchased through Craigslist last November.
Third Roommate Remains at Large
An April 5 warrant alleges Kennison also faces charges for his alleged role in the crime. Kennison remains at large.
The warrant alleges police were able to connect Pena to the crime after finding her work identification in the abandoned Mercedes Benz.
Pena faces charges of conspiracy to commit murder and murder with the use of a deadly weapon, while Kennison is wanted on those same charges.
Turner is charged with murder, according to Clark County Jail records.
Pena and Turner remain in police custody without bail.
Turner’s attorney Brian James Smith told the Associated Press that Turner “categorically denies any role in the death of Dr. Burchard.” It was unclear if Turner has entered a plea.
Pena entered a not guilty plea on Tuesday, her attorney Jess Matsuda tells PEOPLE.
“She is maintaining her innocence and is categorically denying the allegations,” Matsuda says.
According to reports, Burchard was a respected child psychiatrist with an affinity for magic.
