World enews: Ethan Crumbley will plead insanity over Michigan school shooting that killed four students

Michigan school shooting suspect Ethan Crumbley is planning to plead insanity over the deadly massacre that killed four students.

Court documents, filed by his attorneys on Thursday, state that the 15-year-old suspected gunman “intends to assert the defense of insanity at the time of the alleged offense and gives notice of his intention to claim such a defense.”

Mr Crumbley will now be required to undergo a psychiatric exam ahead of a trial.

The teenager is charged as an adult with 24 counts including four counts of first-degree murder and one count of terrorism over the 30 November mass shooting at Oxford High School, after he allegedly took a handgun to school and murdered his classmates.

Four students were killed in the attack – Hana St. Juliana, 14, Tate Myre, 16, Madisyn Baldwin, 17, and Justin Shilling, 17 – and seven other people were wounded in America’s deadliest high school shooting since the Parkland massacre in 2018.

Mr Crumbley’s parents James and Jennifer Crumbley are also charged with four counts of involuntary manslaughter after they allegedly bought their son the firearm as an early Christmas present and left it accessible to him despite multiple warning signs about his behaviour.

News of their son’s intention to plead insanity comes the same day a new lawsuit was filed and just days after Oxford High School reopened for the first time on Monday in the wake of the mass shooting.

Prosecutors said Mr Crumbley exited a bathroom in the school with a firearm which his parents had bought for him as an early Christmas present just days earlier.

The suspect then allegedly opened fire on his fellow students in the hallway as students were changing classes.

He surrendered to law enforcement officers as they arrived on the scene.

The motive for the mass shooting is not clear.

However, prosecutors have revealed a disturbing pattern of behaviour in the days and weeks leading up to the attack.

One day before the massacre, a teacher found Mr Crumbley searching for ammunition on his phone, according to prosecutors.

School staff attempted to alert his parents James and Jennifer Crumbley but messages went ignored and the 15-year-old was allowed to remain in the school building.

On the morning of the shooting, officials said another teacher then found a drawing on the teenager’s desk of a handgun, a bullet and a person being shot.

“The thoughts won’t stop, help me” and “blood everywhere” were scrawled on the note.

That time, his parents were called in to the school and a meeting was held with them, their son and school officials.

The teenager claimed that the drawings were simply designs for a video game, said prosecutors.

His parents fought to have him returned to class, prosecutors said, and were told to get him counselling within 48 hours.

Mr Crumbley was allowed to return to class without his backpack and locker being searched and, just a few hours later, allegedly opened fire in the school.

A lawsuit brought by the families of survivors also alleges that he took bullets to school the day before the attack and showed them off to his classmates.

The suit also claims that he brought a bird’s head to school in a mason jar filled with yellow liquid and left it the bathrooms three weeks before the 30 November massacre.

He pleaded not guilty at an arraignment in December.

Days after the shooting, prosecutors took the unprecedented step to charge the teenager’s parents over the mass shooting.

The couple allegedly bought the gun used in the attack – a Sig Sauer 9mm, model SP 2022 – for their son as a Christmas present four days earlier on Black Friday and left the gun accessible to him.

The 15-year-old allegedly boasted about “my new beauty” on his Instagram account, prosecutors said.

His parents then failed to remove him from the school or to take any action despite the warning signs about his behaviour, said prosecutors.

When news of the shooting spread, Jennifer Crumbley allegedly texted her son “Ethan, don’t do it”.

Meanwhile, James Crumbley called 911 to report a gun was missing and to say that he believed his son to be the shooter, officials said.

In a bizarre turn of events, the couple appeared to go on the run after the prosecutors announced charges against them.

They were tracked down and arrested hiding out in a warehouse in Detroit, where they had withdrawn $6,600 in cash, sold their horses, and bought four burner phones.

They have both pleaded not guilty to the charges and are being held on
