Santa Clarita school shooting: Boy who killed two students dies in hospital as police search for motive
A 16-year-old boy who killed two students and wounded three others in a high school shooting has died in hospital as investigators continue to search for a motive for the attack.
Nathaniel Tennosuke Berhow, succumbed to a head wound he suffered after turning his gun on himself following the attack in Southern California.
Los Angeles Sheriff’s Department said Berhow’s motive “remains a mystery” and investigators have not found any manifesto, diary or suicide note to explain his actions, despite conducting more than 40 interviews.
Gracie Anne Muehlberger, 15, and Dominic Blackwell, 14, were killed in what Sheriff Alex Villanueva described as a "planned attack".
Two girls and a boy were also injured but are recovering.
Berhow opened fire at around 7.30am on Thursday, his birthday, after being dropped off at Saugus High School in the Los Angeles suburb of Santa Clarita.
Mr Villanueva said Berhow counted his rounds and fired six shots before using the last bullet on himself in the attack, which last just 16 seconds.
“As far as we know the actual targets were at random,” the sheriff said.
The police’s conclusion that the attack was planned was based on how Berhow brought the weapon, handled it ably and kept track of the rounds fire, Mr Villanueva said.
In a statement, Gracie Anne's parents Bryan and Cindy Muehlberger said they shared the news of their daughter's death with “unexplainable brokenness.”
The couple added: “We miss her smile, laughter, sweet kisses, and her amazing sense of humour.
“We will even miss her constant pestering for Starbucks and Cold Stone and anything else with lots of sugar in it. It must have been the reason why she was so sweet.”
Berhow was described as a quiet and intelligent child, who had not displayed any signs of violence prior to the attack.
Mr Villanueva said investigators have discovered “nothing out of the ordinary” about him, adding: “He's a cookie-cutter kid that you could find anywhere."
Marisa Randazzo, a psychologist who co-wrote federal guidelines for assessing school shooting threats, said the stereotype of shooters as isolated sociopaths was often inaccurate.
The former chief research psychologist for the US Secret Service said most of the shooters she studied were academically successful and were not social outcasts.
She added they were often pushed by some kind of loss or disappointment, often recent, followed by an inability to cope with a feeling of being overwhelmed.
“These are acts of suicide as much as homicide,” Ms Randazzo said.
Police have interviewed Berhow’s friends, who said he could be introverted but had a good social network and a girlfriend.
The boy’s father was an avid hunter who died two years ago and police said they found several firearms at his home, some of which were unregistered.
The Bureau of Alcohol, Tobacco, Firearms and Explosives is working with police to determine where the teenager got the handgun used in the attack.
