A sheriff's deputy and seven other people were killed in an overnight shooting spree in Lincoln County, Miss., and the suspect is in custody.
The rampage happened at three separate locations in the county, according to a statement from the Mississippi Bureau of Investigation carried by The Associated Press and Reuters.
Durr had a wife and 11-year-old son, and was training to participate in the Drug Abuse Resistance Education program in local schools, according to The Daily Leader.
In a statement, Mississippi Gov. Phil Bryant described the incident as a "senseless tragedy."
"Every day, the men and women who wear the badge make some measure of sacrifice to protect and serve their communities," Bryant said. "Too often, we lose one of our finest."
