At least two people have been killed after shots were fired at Central Michigan University, according to university police.
Local authorities said said a suspect is still at large and have urged everyone on campus - which is located in Mount Pleasant - to take shelter.
The two people killed are not students, but the shooting did occur at the Campbell Hall residence on campus.
A tweet from the official Twitter account for City of Mount Pleasant said the suspect was considered "armed and dangerous". He is said to be 19 years old and wearing mustard yellow jeans and a blue hoodie.
The Mount Pleasant police and Isabella County Sheriff's Department are assisting university police, officials said.
The university said police believe the Friday morning shooting “started from a domestic situation.”
The shooting occurred on the last day of classes before the university's spring break. Parents who were trying to pick up students were told to stay off campus and go to a local hotel where staff would assist them.
All the schools in the Mount Pleasant have been put on lockdown, as has the university campus.
Halie Byron, 20, said she locked herself in her off-campus house, about a 10-minute walk from Campbell Hall. She had planned to run errands before traveling home to the Detroit area.
“It's scary thinking about how easy a shooter can come into a college campus anywhere — a classroom, a library. There's so much easy access,” Ms Byron told the Associated Press.
Michigan Governor Rick Snyder tweeted that he was in "constant contact" with Michigan State Police.
"The priority right now is the safety of those still on campus and I thank all first responders involved for their swift action," he tweeted.
The university, which has about 20,000 students, is in Mount Pleasant, about two hours northwest of Detroit.
