NEW ORLEANS — NOPD says an officer providing security at a high school basketball game in New Orleans was fatally shot by a man who was denied entry to the game because he was not wearing a mask.

According to Orleans Parish Sheriff’s Office records and NOPD, 35-year-old John Shallerhorn was arrested for first degree murder of a police officer.

Records also show Shallerhorn was booked on an armed robbery charge.

Friday night, near the end of the first quarter of the Carver vs Warren Easton game, multiple gunshots were fired. The officer was pronounced dead at the hospital.

Superintendent Shaun Ferguson says the officer was on the Tulane University force and a reserve constable with the Second City Court in Algiers.

As Shallerhorn was escorted out, he shot the officer twice NOPD said. Shallerhorn placed the gun on the ground and was arrested on scene.

Shallerhorn is being held without bond.
