Two people have been killed in a shooting at Central Michigan University, school authorities said on Friday.
The deceased were not students and the shooting is believed to have resulted from a "domestic situation," the university said in a statement, adding that no one else had been injured.
The 19-year-old suspected gunman is a black male wearing mustard yellow jeans and a blue hooded jumper, officials in the city of Mt Pleasant said.
He is still at large and the campus remains on lockdown.
The incident comes less than three weeks after a shooting at a Florida high school left 17 people dead and more than a dozen others injured.
The Valentine's Day attack brought to life a student-led gun control movement which has placed pressure on national lawmakers to pass legislative changes limiting gun sales to people below the age of 21 and to those with mental health issues.
The shooting took place on the fourth floor of a campus dormitory, according to WDIV television.
Students from Marjory Stoneman Douglas High School in Parkland have made powerful appeals for change to permissive US gun laws in the wake of the shooting. They returned to campus on Wednesday amid heavy security.
The Florida gunman, who had a history run-ins with law enforcement, used a semi-automatic assault rifle in the shooting.
President Donald Trump had called for training and arming some teachers, tougher background checks and a potential increase to the minimum age for rifle purchases.
But the powerful National Rifle Association gun lobby said that Trump was opposed to gun control after meeting with him on Thursday.Last updated: March 02 2018 08:02 PM
