A man suspected of gunning down a Mississippi college professor in his campus office has died of a self-inflicted gunshot wound after a day-long manhunt, according to media reports on Tuesday.
Shannon Lamb, a social science instructor at Delta State University, killed himself after being cornered by police as they tried to initiate a traffic stop, the Jackson Clarion Ledger and WALA-TV reported.
Lamb was being sought in connection with the early Monday killing of Ethan Schmidt, an assistant professor of American history at Delta State, as well as another woman, authorities have said.
The shooting left students and staff in Cleveland, Mississippi, on edge for several hours as police locked down the school and searched buildings following reports of active gunfire.
Cleveland Police Chief Charles "Buster" Bingham would not comment on Lamb's possible connection to Schmidt.
The chief said investigators were looking into the possibility that Lamb was involved in an earlier homicide in Gautier, a town five to six hours south of Delta State on the Mississippi Gulf coast.
Gautier police detective Matt Hoggatt told CNN that police responding to the scene of a shooting reported there shortly after 10 a.m. on Monday found a woman shot and killed.
Delta State officials said no students were injured in the campus shooting, which occurred in Jobe Hall.
All classes were canceled on Monday, as well as Tuesday, when events had been planned to commemorate the university's 90th anniversary.
The slain professor earned a doctorate in early American history and Native American history from the University of Kansas and taught for six years at Texas Tech University before joining the faculty at Delta State, according to his school biography.
Reports of shots fired prompted the lockdown, with students receiving a text alert at 10:40 a.m., the sheriff's office said.
More than 4,000 students are enrolled in the public university, 120 miles (195 km) northwest of Jackson, Mississippi.
Police from several local and state agencies were on campus assisting in the investigation, and nearby public schools were also locked down as a safety precaution.
