A Michigan teenager was ordered held without bond on Wednesday after being charged with first-degree murder in the deadliest US school shooting of the year, which killed four students and wounded seven other people.
Ethan Crumbley, a 15-year-old sophomore at a high school in Oxford, Michigan, about 40 miles (65 km) north of Detroit, was charged with a slew of criminal counts in Tuesday's shooting spree, Oakland County Prosecuting Attorney Karen McDonald said.
"I am absolutely sure after reviewing evidence that it isn't even a close call," she told a briefing. "It was absolutely premeditated."
In addition to four counts of first-degree murder, Crumbley faces one count of terrorism causing death, seven counts of assault with intent to murder and 12 counts of possession of a firearm in the commission of a felony, she said.
The shooting spree was the deadliest on US school property this year, according to Education Week. It was the latest in a decades-long string of deadly American school shootings.
