The two divorced 15 years ago, but remained friends.

“We lost one of our beloved professors today”, Michelle Roberts, vice president of university relations at Delta State, told reporters. He was teaching two online courses this semester.

Mr Mitchell said police helicopters were in the air, and officers were sweeping buildings.

Lamb then led police in a 12-hour auto chase, which ended when he told police officers “wasn’t going to jail” before turning the gun on himself.

Unfounded speculation early in the investigation had centered around a possible love triangle between Lamb, Schmidt and Amy Prentiss, who lived with – and was ultimately killed by – Lamb.

“He was really jittery, like there was something wrong with him”, Beavers said.

“We are continuing our investigation to search for a motive in the homicide of Amy Prentiss“, Gautier police Detective Matt Hoggatt said in a release. But there wasn’t a note or anything left behind at this scene.

“We have to get an answer to what is going on”. We don’t have answers yet.

“It was supposedly that he was bitten by a spider or something”, Bingham confirmed.

Police began to follow Lamb but did not attempt to apprehend him as he drove. He had a book bag on his shoulder, indicating that he was either entering or leaving, Bolivar County Deputy Coroner Murray Roark said.

His vehicle was still running in the driveway.

A day after the school shooting forced students and staff to hide behind locked doors, authorities were still trying to piece together what motivated Lamb, who had not criminal record. Lamb grew up in the area. He started working there in 2009 and taught geography and education classes. He received a doctorate in education in the spring.

News Channel 3 reports that police were able to speak with Lamb “at some point” between the murder of Schmidt and the time at which Lamb was pulled over.

Police in Gautier said Shannon Lamb called them at 10:00 local time (14:00 GMT) on Monday and said he had shot and killed someone, but without any explanation. He also asked police to take care of their dog and to reach out to Prentiss’s family, The Washington Post reported.

“He’s a sweet dog”, the man said.

Prentiss’ ex-husband said her daughter is “devastated” by her mother’s death. “He always sees the big picture and I think had he been alarmed, it might have alarmed me more”, she said. He said Prentiss and her daughter were “absolutely best friends”.
