A Wyoming girl fatally shot mother Theresa McIntosh after an argument over a stolen tablet

A troubled 14-year-old boy has been arrested after allegedly fatally shooting his mother in the back of the head after discovering she was holding a tablet from one of her customers.

Havoc Leone is accused of killing his mother, Theresa McIntosh, 41, on March 7 at their home in Cheyenne, Wyoming – and was charged with murder, where he will be tried as an adult, the Wyoming Tribune Eagle reported.

McIntosh’s death was initially investigated as a suicide. But after police and medical personnel came under suspicion, Leone later allegedly confessed to police that he shot his mother with his own gun after an argument over a stolen metal, according to the newspaper, citing court documents.

Leone also allegedly told police that he had thought about killing his mother several times in the past when she told him to do things he didn’t want to do, the documents said.

The teenager – who had stolen other things in the past – overheard his parents arguing about the latest theft.

McIntosh called him an “old man” and a “thief,” which angered him.

Around 11:30 a.m. at the time of the shooting, McIntosh told Leone to finish his homework while he did a puzzle in his room.

The two and the son started arguing over the tablet and McIntosh searched for the password written in the notebook the boy had downloaded and threw it into the room, the 14-year-old boy told law enforcement.

The girl threw the notebook on the floor and grabbed the gun that was hidden in her room.

When his mother bent down to pick up the notebook, he allegedly shot her in the head, according to court documents.

Leone’s father was playing video games in the basement and said he heard a “pop” after fifteen minutes, but believed it was the sound of a balloon popping because he was wearing noise canceling headphones.

About an hour later, Leone’s father went to the main level of the house, where he saw the teenager outside his bedroom who said he didn’t know what happened as it “just went off,” referring to the gun, the US Sun reported, citing a Laramie County Sheriff’s affidavit.

According to court documents, Leone’s father gave McIntosh first aid, but she did not respond and called 911.

A black Taurus 9mm handgun was found near McIntosh’s body, which puzzled Leone’s father as it was often kept in McIntosh’s car where a full magazine is kept, but never chambered, according to court documents.

The girl initially said her mother had given her the gun – but later said she stole it from her car after a ‘huge argument’ a stone’s throw away, Oil City News reported, according to a court report.

Leone’s father told police that his son knows how to handle and handle guns — adding that he “doesn’t know to point a gun at someone unless he plans to shoot them dead,” according to the Tribune.

McIntosh was taken to an area medical center before being airlifted to UC Health in Fort Collins, Colorado where he died from his injuries later that day.

Hospital staff said the gunshot wound — which was behind and above McIntosh’s right ear above his neck — did not appear to be a “contact wound,” consistent with suicide attempts involving firearms and there was no visible exit wound, typical of a self-inflicted gunshot, the Tribune reported.

The grieving father told law enforcement, “I don’t want to think about what I think happened…I don’t even want to put it into words…and I don’t want to think that because it’s something that a parent really shouldn’t think about…”

“It would be much easier to accept that he killed himself than my son who tried to kill him,” he said, according to court documents.

A $500,000 bond has been set for the youth, according to Oil City News.
