CLEVELAND, Miss. (AP) — The latest on a shooting at Delta State University that left a professor dead .

The professor killed in his office at a university in Mississippi has been identified as Ethan Schmidt, who worked in the history department.

According to Schmidt’s bio on the Delta State web site, the Marion County native  earned his B.A. and M.A. at Emporia State University and his Ph.D., at the University of Kansas.

Murray Roark, deputy coroner in Bolivar County, says Schmidt was killed in his office Monday morning at Delta State University.

Authorities say they are searching for a car believed to be driven by a person of interest in the slaying.

Mississippi Highway Patrol spokesman Johnny Poulos says investigators believe Shannon Lamb is driving a 2011 black Dodge Avenger with a Mississippi license plate and the number STF 015. The license plate also has the word “Stone” as a designation for Stone County.

Lamb has been called a “person of interest” in the shooting of history professor Schmidt at Delta State University on Monday morning. Police also say they have information suggesting he may have been involved in another slaying in south Mississippi.

The 3,500-student university is in Cleveland, in Mississippi’s Delta region near the Arkansas-Mississippi state line.
