Killer Kids: Horrific Crimes Committed by Children

Child Criminals: You’ll Be Shocked by These Horrific Crimes Committed by Children


1. A 15-year-old boy murders his two adopted brothers

Killer Kids: In May, 2013, a 15-year-old Utah boy was babysitting his siblings while his mother was out (his father was active duty military and had been deployed in another state for several years at the time). When the mother returned, she found her adopted 4-year-old and ten-year-old boys stabbed to death in their home. Her 15-year-old boy was missing. Police later found him running about five miles away. They declined commenting on his mental state.

The boy ended up pleading guilty and is currently receiving counseling while in the juvenile system until he turns 21, at which point he’ll be transferred to prison and serve 15 years to life.

2. A 12-year-old boy shoots his mom over chores

Killer Kids: A 12-year-old Arizona boy shot his mother to death over a chores dispute in 2009. The boy shot her eight times with a .22-calibur pistol. He knew how to use the gun because the mother’s boyfriend taught him “for emergencies and self defense.”

According to Digital Journal, Judge James Conlogue found the boy guilty, as a juvenile, for premeditated murder in the Cochise County Superior Court in the southern Arizona town of Bisbee.

3. Mary Bell, the 11-year-old serial killer

In 1968, Mary Bell killed two children with her bare hands (and a pair of scissors to mutilate one of the bodies). During the course of the investigation, police found Bell’s behavior to be “evasive” and suspicious early on. Bell was a troubled child with a horrible past who was often described as violent and dishonest.

When Bell’s friend and accomplice, Nora, told police that Bell was responsible for the murders, Mary was convicted of manslaughter due to diminished responsibility, in part due to the psychological assessment presented at the trial. Bell was considered psychopathic by various assessments.

Killer Kids: The “Medicine Hat Girl,” (named after where the murders took place) 12 at the time, killed her family with the help of her 23-year-old boyfriend. The girl testified that her boyfriend broke into her home, and ordered her to stab her family members before he finished them off. They then stole her mother’s purse and returned to the boyfriend’s trailer.

Because the two had had previous conversations about killing the girl’s family, they were both found guilty.

The mother was on the living room couch while her fiancé slept with their 5-year-old daughter in the next room over.

In response, the Detroit mayor, Dave Bing, “asked Detroiters not to stand idly by while children become victims of crime. But at the same time, he demanded parents take more responsibility for their children’s actions.”
