A judge in Texas sentenced Adam Steven Barney, now 18, to life in prison for murder, according to the Collin County District Attorney’s Office.

“The victim in this case was brutally murdered by her own son, who she spent his entire life trying to help overcome his dark characteristics. But in the end, the evil in Adam Barney could not be helped," Collin County District Attorney Greg Willis said of the loss of the "beautiful wife and mother."

On Jan. 3, 2021, police in McKinney, Texas, were called to the family’s home after the father called 911 to say his son killed his wife.

When officers arrived, the father gave them video footage from inside the house.

It showed that Barney attacked his mother from behind as she sat on the living room couch, prosecutors noted. He struck her in the head 11 times with a hammer and then strangled her until she stopped breathing.

When the dad came out of the bedroom, Barney attacked him with a screwdriver and fled the house.

Seven hours later, police found Barney walking down the street.

During the trial, prosecutors detailed Barney’s long history of violence, manipulation and unprovoked aggression toward others. A journal entry showed he made comments about killing his family when he was just 7 years old.

A psychologist testified he had traits of a psychopath.

Defense attorneys tried to get the case heard in juvenile court but were not successful. They said the jury chose not to see past the actual crime, according to the Dallas Morning News.

“While respecting the decision of the jury, the defense team did our absolute best to humanize our client by presenting an extensive history of mental health challenges and sexual abuse suffered by a 15-year-old boy,” a statement from the defense noted, according to the report.
