CHICAGO - A university student who fatally shot his parents on his school campus in the US state of Michigan was arrested without incident after an hours-long manhunt, officials said on Saturday.
The shooting had put the Central Michigan University campus on lockdown on Friday morning, trapping students in classrooms and dormitories until mid-afternoon while police conducted an expansive search for the 19-year-old suspected gunman.
James Eric Davis, described as a university student, was turned in by "an individual on a train passing through the north end of campus shortly after midnight", university officials said. Officers arrested him without incident.
The suspect is accused of killing his father, who was a police officer, and mother in a dormitory building in what a university police spokesman described as a "family-type domestic issue".
There were no other casualties.
The college campus in the city of Mount Pleasant in central Michigan was on lockdown between 8.30am (1330 GMT) and about 3pm (2000 GMT).
Suspect known to police
Davis, who was a resident of nearby Illinois state but attending college in Michigan, was known to law enforcement.
Police had taken him to a hospital the night before for what was believed to be a "drug-related type of incident -- an overdose or a bad reaction to drugs", campus police spokesman Larry Klaus told a news conference.
He was then released to hospital staff, Klaus said.
It was unclear what kind of weapon Davis used or how he acquired it.
The state of Michigan allows for the concealed carrying of a handgun with a permit, but Central Michigan University does not allow guns on campus.
