Kalesha Marie Peterson, 37, of Fulton, was jailed Friday morning on suspicion of felony second-degree murder and unlawful use of a weapon, Callaway County Sheriff Clay Chism said Friday.
She was booked by Fulton police, who said she called 911 at 10:22 p.m. Thursday and told operators she had accidentally shot her boyfriend who needed immediate medical care.
The shooting victim was David Dalton, 37, police reported.
Officers at Peterson's residence in the 400 block of East First Street in Fulton found Dalton in a bedroom with a gunshot wound to the head.
Officers attempted life-saving measures until medics arrived, according to a news release from Fulton Police. Medics attempted to treat Dalton and declared that he was dead.
Peterson told officers at the scene she had been drinking and later made statements to those officers suggesting she was intoxicated. A bottle of whiskey was found in the bedroom where Dalton was located.
Peterson was interviewed at the Fulton Police Department, according to the news release.
She told police she and Dalton had been watching a movie and drinking alcoholic beverages that evening. She said that at some point Dalton suggested the two play out a scene in the movie that involved a firearm and that the two retrieved a handgun kept in the bedroom.
Peterson described the handgun, which had been observed by officers who responded to the scene. That firearm is described as a Taurus brand, .38-caliber revolver. Two spent shell casings were found in the revolver.
Peterson stated that she had the gun in her hand when it discharged.
Peterson also told officers she had attempted to stop the bleeding from the gunshot wound to Dalton's head.
Peterson said Dalton had used the firearm some weeks prior and had not removed one of the spent shell casings found in the course of the police investigation.
While at the Fulton Police Department, Peterson voluntarily provided a breath sample which confirmed that she had recently consumed an alcoholic beverage. During the course of Peterson's interview, Peterson admitted she had been drinking whiskey and was intoxicated.
Peterson also told police she was taking several medications. While at the residence, officers noted prescription medications in bottles with Peterson's name, some of which included medications known to increase impairment when used with alcoholic beverages.
Peterson told officials she is employed at Fulton State Hospital, Chism said.
