A history professor at Delta State University was fatally shot in his office on Sept. 14.
Assistant professor Ethan Schmidt was found dead by a shot to the head in his office in Cleveland, Mississippi.
Fellow professor Shannon Lamb was suspected of the shooting as well as the murder of Amy Prentiss, who Lamb lived with.
When the authorities found Lamb in his vehicle, he got out of his car and fled on foot. Lamb pulled out a gun and killed himself in the woods just north of Greenville, Mississippi.
The authorities have not found evidence pointing to Lamb as the killer, and have not disclosed any known motive.
