A 47-year-old Missouri mother is accused of murdering her 16-year-old son by shooting him multiple times as he slept, then obtaining a knife from the kitchen to stab him, claiming she wanted to “relieve his pain.”

Krista Roy was recently apprehended and charged with first-degree murder and armed criminal action in connection with her son’s brutal killing, according to court records reviewed by Law&Crime.

As per a probable cause affidavit, St. Charles Police Department officers responded to a home on Lightfoot Drive for a wellness check request from the victim’s friends. The callers, described as being “extremely close to the victim,” informed police that they hadn’t heard from him in days, calling this “highly unusual behavior.”

When first responders arrived, they noticed a “foul odor” emanating from the home. Inside, they found the victim dead in his bed from “multiple gunshot wounds and stab wounds,” ruling the death a homicide.

A knife that appeared to be covered in blood and ballistic evidence were recovered from the scene.

In interviews, the friends who called for the welfare check described the victim as someone who “loved life” and “was not suicidal.” They referred to the victim’s mother as “strange” and “minimally involved in his life.”

Recounting the last encounter with the victim, one friend mentioned they were together the night of Friday, Sept. 26, until around 2 a.m. on Sept. 27, when the friend dropped him at his home.

“The friend informed detectives that he had attempted to contact the victim several times over the course of the weekend but was unable to reach him,” the affidavit says.

Investigators said they also discovered that the victim’s mother, whom they identified as Roy, had attempted to commit suicide earlier in the day Monday and was still being treated at a local hospital. Detectives responded to the facility and, upon Roy’s release, took her into custody in connection with her son’s murder and brought her to the police department for questioning.

Police say that after voluntarily waiving her Miranda rights, Roy confessed to killing her son in a recorded interview, revealing grisly details about the teen’s final moments.

“Roy admitted to retrieving a firearm from her ex-husband’s residence on 09/26/2025, with the intention of shooting the victim and herself,” police wrote in the affidavit. “Furthermore, Roy admitted to shooting the victim multiple times while he was sleeping. Roy further confessed to lying in the bed with the victim, caressing him, and hearing the victim cry out ‘Mommy’ several times.”

When her son did not immediately die from the gunshot wounds, Roy allegedly admitted that she continued her efforts to end his life.

“Roy admitted to getting up from the bed, retrieving a knife from the kitchen, and stabbing the victim,” police wrote. “Roy stated she did this to put the victim ‘out of his pain.’ When asked if she wanted to kill the victim, Roy replied, ‘Yeah.'”

Roy was transported to the St. Charles County Jail where she is currently being held on a $1 million cash-only bond, records show. It was not immediately clear when she was scheduled to appear in court.
