A 43-year-old man was identified as the person who killed three at Michigan State University (MSU) on Feb. 13.

Anthony McRae, 43, carried out the shootings at the school, law enforcement officials said Tuesday.

Some students were shot inside Berkey Hall. McRae then went to the MSU Union building nearby and kept shooting, officials told a briefing.

The first call to police about shots being fired came in shortly before 8:30 p.m.

The suspect was located in Lansing, off campus, based on a tip. McRae killed himself, according to law enforcement.

Three students were killed and five others were left injured.

The injured students were all in critical condition on Tuesday morning.

Law enforcement officials said they have not pinpointed a motive. They said McRae has no affiliation with the university.

“I know everybody wants to know what the motive is. We don’t have an answer,” Chris Rozman, interim deputy police chief for the school, told reporters.

McRae was charged after admitting to having a gun on him without a permit during an encounter with a police officer at approximately 1:30 a.m. on June 7, 2019, according to the Michigan Department of Corrections.

McRae said he took the gun with him as he went to the store to buy cigarettes because he feared for his safety. According to court documents, McRae said he was attempting to get a concealed carry permit.

McRae was charged with a felony but ended up pleading guilty to possession of a loaded firearm, a misdemeanor, and the felony was dismissed. McRae relinquished the gun as part of the plea deal.

McRae was placed on probation on Oct. 24, 2019, and discharged on May 14, 2021.

“He did not have any issues while on probation and never had a positive drug test,” a Department of Corrections spokesperson told The Epoch Times via email.

Melinda McRae, McRae’s sister, told CNN she was “shocked” and did not know why her brother carried out the shooting.

The sister said her brother was sorrowful following their mother’s death and lived in shelters in various cities.

She had not seen him since their mother’s funeral in 2020.

“I’m just so sorry about the innocent people that got killed,” she said.

Dr. Denny Martin, interim president and chief medical officer at the Edward W. Sparrow Hospital, told reporters that four of the five victims who were transported to the hospital required surgery. All five are in critical condition.

Three other students were found dead at the scene, law enforcement said.
