New Orleans Campus Officer Murdered Outside of Basketball Arena

The New Orleans Police Department says Tulane University Police Officer Martinus Mitchum was shot and killed Friday night while providing security for a basketball game at George Washington Carver High School.

John Shallerhorn, 35, was booked early Saturday morning for armed robbery and 1st degree murder of a police officer.

The NOPD says Shallerhorn arrived at the school and was refused entry due to not having on a mask.

A physical altercation ensued with a school employee. The Tulane officer intervened and escorted the suspect out, WVUE reports.

As Shallerhorn was leaving, he shot the officer twice, then placed the weapon on the ground and was taken into custody, police say.

Just moments before Shallerhorn attempted to enter the school, police say he robbed a man at gunpoint in the parking lot.
