Delta State University police chief Lynn Buford told The Associated Press that officers heard a single gunshot before finding Lamb wounded. He was taken to a local hospital where he was pronounced dead.

Lamb,  a geography and social science education instructor, was suspected of shooting history professor Ethan Schmidt at his desk at Delta State University on Monday morning.

Police believe that before he killed Schmidt, he murdered his domestic partner, 41-year-old Amy Prentiss, at their home in Gautier.

According to reports, Lamb believed Prentiss was in a relationship with Schmidt, although authorities have declined to confirm a motive.

Following the shooting, the university campus was on lockdown Monday afternoon before buildings were later evacuated.

All campus classes were canceled on Monday, as well as Tuesday, when events had been planned to commemorate the university's 90th anniversary.

The lockdown started at around 10:45 a.m. local time. Students, faculty and staff were advised to take shelter and stay away from any windows. State and local law enforcement agencies have responded.

"Fortunately for us, our public safety officers and university officials have trained many of us for active shooter situations," Don Allan Mitchell, an English professor, wrote in a Facebook message to The Associated Press.

"Many students are locked-down in classrooms, and professors and staff members are telling them the protocol. Plus, we are all texting and Facebooking each other to make sure we are safe."

He said police helicopters were flying overhead, and officers were going through buildings.

Bill Hays, an English professor, said the university did a poor job of communicating about the situation. "It's really frustrating because there is no campus-wide updating from a central command center. Everything we're getting is just rumors," Hays said.
