Michigan authorities on Tuesday said they have "no idea why" a 43-year-old man killed three Michigan State University students and wounded five others before turning the gun on himself, the latest in an epidemic of mass shootings on US campuses.
The gunman, identified as Anthony Dwayne McRae of Lansing, Michigan, shot himself to death after the rampage on Monday night, Jim Tarasca, special agent in charge of the FBI's Detroit office, said at a briefing. McRae had no known affiliation to the university in East Lansing, about 90 miles (145km) northwest of Detroit.
Police have "no idea why he came to campus to do this tonight," said Chris Rozman, interim deputy chief of the Michigan State University police force.
Sophomore Claire Papoulias was sitting in her Cuban history class when the gunman entered her classroom. She said she dropped to the floor when she started hearing gunshots directly behind her head.
"I will never forget the screams of my classmates because they were screaming in pain for help," Papoulias said on NBC's Today show. "Someone was yelling that there was a shooter and everybody needed to get down on the ground, and at that moment I thought that I was going to die. I was so scared."
The five wounded students were in critical condition at EW Sparrow Hospital where surgery was performed on four of them, Dr Denny Martin, the hospital's interim president and chief medical officer, said during the briefing as he struggled to keep his composure.
"I am filled with rage that we have to have another press conference to talk about our children being killed in our schools," Congresswoman Elissa Slotkin, who represents the area, said. "If this is not a wake-up call to do something, then I don't know what is."
The shooting took place about 30 miles south of Oxford, Michigan, where a teenaged gunman in 2021 used a rifle his father bought as a Christmas present to kill four students at the local high school.
Monday's shooting came a day before the five-year anniversary of the Valentine's Day massacre at Marjory Stoneman Douglas High School in Parkland, Florida, which left 17 students and teachers dead.
"Another place that is supposed to be about community and togetherness is shattered by bullets and bloodshed. We know that this is a uniquely American problem," Michigan Governor Gretchen Whitmer said during the briefing, noting that she spoke to President Joe Biden about the incident.
Among those killed in the shooting were junior Alexandria Verner of Clawson, Michigan, and sophomore Brian Fraser of Grosse Pointe, Michigan, university police said in a statement.
Verner was a 2020 graduate of Clawson High School, near Detroit, local ABC affiliate WXYZ-TV reported, citing a letter from the district's superintendent.
"She was a tremendous student, athlete, leader and exemplified kindness every day of her life!" Superintendent Billy Shellenbarger wrote to families, WXYZ-TV reported. "If you knew her, you loved her."
At the request of the family, officials declined to provide details about the third student who was killed.
Timeline of shootings
At about 8.30pm local time, police received a call that shots were fired in Berkey Hall, an academic building on the school's northern campus.
Officers arrived within minutes and found several people shot, including two who were deceased. Police then began receiving calls about another shooting at a nearby building, where officers found the third fatality, Rozman said.
Police located the suspect in Lansing at 11.35pm, about three hours after the first report of a shooting. He died of a self-inflicted gunshot wound, Rozman said.
About an hour earlier, MSU police had released two still images of the suspect from surveillance video that showed him walking into a building, then mounting a short flight of stairs, wearing a jacket, a baseball cap and a black mask over his lower face. He was holding what appeared to be a pistol in one hand.
Rozman said a citizen who had seen the photos called in a tip to police that led to authorities finding the gunman.
Authorities did not disclose the type of weapon used during the rampage, nor whether he was armed with more than one gun.
They also shared little about the shooter.
But an 85-year-old neighbor of McRae told Reuters that the suspect was "a real hell-raiser" who would sometimes shoot a semi-automatic pistol on the property where he lived with his father.
"We'd hear the gun fire all the time and then it seemed the cops were always down there for something," said the neighbor, who wished to remain anonymous.
