“Law enforcement personnel responded and arrested the suspect without incident,” the statement said.
The shooting came just over two weeks after 17 people were killed at a high school in Parkland, Fla., and amid a national conversation about gun control and gun rights. Near Central Michigan’s campus in Mount Pleasant, about 150 miles northwest of Detroit, public buildings and schools were placed on lockdown.
Lt. Larry Klaus of the university police, said Friday that the younger Mr. Davis had been taken to a hospital by the police on Thursday evening for what “officers believed might be a drug-related” incident, perhaps an overdose or a bad reaction to narcotics.
Lieutenant Klaus said officers had found clothing alongside railroad tracks that may have been discarded by Mr. Davis.
The hunt for Mr. Davis and the lengthy lockdown complicated the beginning of spring break at Central Michigan and led to the postponement of a men’s basketball game. The game was later rescheduled for Saturday morning, but will be closed to the public. More than six hours after the shooting, police officers went building to building to evacuate students. Parents who arrived to pick up their students were initially told to wait at a hotel.
As the search continued, Gov. Rick Snyder of Michigan spoke alongside university leaders, promising assistance for students rattled by the shooting.
“We had two people that were killed in a residence facility: that’s traumatic,” said Mr. Snyder, a Republican. “I hope everyone can rally and, to the degree you see something, say something.”
