DENVER — A man who killed his wife while she was calling emergency responders to get him help took prescription pain medicine and ate marijuana candy hours before the shooting, according to court documents.
Richard Kirk, 47, bought two marijuana edibles Monday, the night he is accused of shooting his wife, Kristine Kirk, in the head, according to a search warrant issued in the case. Officials have not released the 911 call or dispatch records.
Richard Kirk's blood will be tested to determine what drugs he has in his system.
He is in jail without bond on first-degree murder charges.
Police officers responding to the scene said Richard Kirk was "rambling to himself" in the back of the patrol car, telling officers he was a religious man and a member of the Church of Jesus Christ of Latter-day Saints. Authorities also say he confessed to the killing.
A detective, trained in effects of marijuana and prescription pills, documented that Richard Kirk "appeared to be under the influence of some type of controlled substance and/or prescription pills based upon his speech patterns, his inability to focus and his pupils." He told police that he had taken medication for back pain.
Investigators found a receipt and a package for the candy — Karma Kandy Orange Ginger — in the basement of the family home, according to court documents. Richard Kirk bought that and Pre 98 Bubba Kush Pre-Roll, a pre-rolled marijuana cigarette, less than three hours before his wife called 911.
Surveillance video at a pot dispensary also shows Richard Kirk looking at several items Monday before making his purchases. One piece of Karma Kandy has more than 100 milligrams of THC, the psychoactive ingredient in pot; 10 milligrams is Colorado's definition of one edible dose of THC. The state won't be requiring potency testing until May.
A little before 9:30 p.m. Monday, Kris Kirk, 44, told the 911 operator that her husband "had taken some marijuana and possibly some prescription medication for back pain" and was hallucinating. Their three young children were in the house.
She pleaded with dispatchers to hurry and send officers because her husband had asked her to get a gun and shoot him. She said he was talking about the end of the world and she was "scared of what he might do."
"On the recorded call, Mrs. Kirk can be heard telling Richard to stay down and yelling for her kids to go downstairs. At one point, Mrs. Kirk tells the 911 operator 'please hurry' because he was scaring the kids and he was 'totally hallucinating,' " according to the search warrant affidavit.
Kris Kirk was on the phone with a dispatcher for about 12 minutes before her husband took a gun out of their safe and killed her. Police also are investigating their response to the call.
The Denver Police Department has struggled with slowing response times in recent months as the number of officers has decreased because of retirements, departures and budget cuts that kept the department from hiring for five years.
When Kris Kirk realized that her husband had removed the gun from its safe, she panicked.
"She next related that he had the gun, and she did not know where to go," documents say. "Within a few seconds Ms. Kirk can be heard screaming." She died before she could be taken to a hospital.
Richard Kirk does not remember anything of the incident, his brother, Lance Kirk, said Thursday.
"He's hurting. He's hurting real bad," Lance Kirk said.
