A mother who beat her young child to death after he wet the bed has been sentenced to 40 years in a federal prison.
Katrina Shangreaux, 30, pleaded guilty to second-degree murder for the death of her 2-year-old son Kylen Shangreaux on July 17. Kylen had been killed at their Porcupine, South Dakota home on July 28, 2016, according to the Rapid City Journal, a South Dakota-based news organization.
An autopsy found Kylen died from blunt force trauma after Katrina admitted to attacking the child with a studded belt, throwing him to the ground, kicking, punching, and biting him. His body was found to have been 70 percent covered in bruises and with broken ribs and bleeding in the brain. Cigarette burns were found on the corpse and the child's genitals had also been mutilated, Assistant U.S. Attorney Sarah Collins said at the sentencing hearing.
The child had over 111 external injuries at the time of his death, Collins said.
A neighbor told the FBI that she had heard screaming coming from the house at around 5 a.m., according to the Kansas City Star.
In court, Katrina said she attacked Kylen after he had wet the bed and gave her "a sideways look." She claimed she had been under the influence of pain medication and alcohol at the time.
Katrina admitted to waiting hours to call the police after killing the child, at first saying that he had choked on apple juice. With the help of her mother, Sonya Dubray, she cleaned the crime scene before officers arrived.
Dubray has since pleaded not guilty to hindering the investigation, according to the CBS News.
"Potty training was the catalyst for the child abuse and (Dubray) knew the statement and representation was false," prosecutors said in court documents.
Kylen's paternal relatives had begged the courts to be harsh on Katrina.
“You’re the last person who can give Kylen the justice he deserves,” Kylen's aunt Angie Shangreaux told U.S. District Court Chief Judge Jeffrey Viken during the proceedings, according to the Rapid City Journal. “I’m begging for what would be a lifelong sentence for her.”
"I hate you," Angie added to Katrina. "I will never forgive you. … You deserve hell.”
Kylen had been in Angie's care before a custody battle forced her to return him to Katrina.
Katrina expressed remorse in court.
"[It was] one day that went wrong,” Katrina told the judge, according to the Rapid City Journal. “Not a second, not a minute goes by every day that I don’t think about losing him.”
