The attorney for a former Playboy model accused with two other people of killing a California psychiatrist in Las Vegas said his client had no role in the doctor’s death.

Kelsey Nichole Turner, 25, “categorically denies any role in the death of Dr. [Thomas Kirk] Burchard,” Brian James Smith, the model’s attorney, told The Associated Press. Turner was arrested on March 21 in Stockton, California. She is currently behind bars at the Clark County Jail in Las Vegas and being held without bail.

Burchard, 71, was discovered in the trunk of a blue Mercedes-Benz on March 7 near the entrance to the Lake Mead National Recreational Area in Las Vegas. Investigators spoke with Turner’s landlord, who told them the doctor paid for her rent on March 1 and “her lease was paid through June 2019,” KSNV reported which obtained the court records stated.

Burchard's girlfriend of 17 years, Judy Earp, said that Burchard had given Turner at least $300,000 over the years that she knew of, and that she considers Turner "as evil as Charles Manson." He reportedly gave a number of other women money over the course of their relationship, she said. Earp added that she believed Burchard was in the early stages of Alzheimer's at the time of his death.
