A 10-year-old boy in the United States allegedly shot his mother to death over her refusal to purchase Oculus virtual reality headset on Amazon.

The next day and bought an Oculus Virtual Reality headset for himself.

According to the New York Post, the boy was charged with first-degree homicide and is being held in a juvenile detention facility.

The media outlet said he told his elder sister about the incident and claimed he was twirling the weapon around his finger when it went off. 

The 26-year-old sister reported the case to the police but relatives questioned his story, which he later confessed to the police that he pointed the gun at his mother.

The 10-year-old boy’s aunt claimed he told her that he pointed the weapon at his mom and shot her in the face. 

“I’m really sorry for what happened. I’m sorry for killing my mom,” the boy’s statement read, according to the aunt.

Relatives told authorities that the 10-year-old son has a history of disturbing behaviour, which included an incident where he swung his puppy by its tail when he was just age four.

They also claimed that he caused an explosion six months ago, when he set a balloon containing a flammable liquid on fire.

The relatives said the boy had told them he hears imaginary voices.

During interviews with the police, he told them he aimed the gun at his mom and tried shooting into the wall to “scare her,” but it struck her when she walked in front of him.

He told investigators that he got the gun from the lock box because his mom woke him up early at 6:00 a.m. instead of 6:30 a.m, adding that she wouldn’t purchase his favourite headset on Amazon.

The 10-year-old boy has been charged as an adult with first-degree reckless homicide, he will be appearing at Center in Milwaukee on December 7.

The legal representative of the boy, Angela Cunningham, said she was still gathering information about the case.

“This is an absolute family tragedy. I don’t think anybody would deny or disagree with that. The adult system is absolutely ill-equipped to address the needs of a 10-year-old child,” Ms Cunningham said.
