An off-duty police officer headed home after a shift Sunday night struck and killed a 70-year-old bicyclist, according to the New Orleans Police Department.

The bicyclist was traveling northbound on Martin Luther King Boulevard around 11 p.m., police spokesman Officer Hilal Williams said, when he ran through the red light at the intersection of South Claiborne Avenue. Officer Eric Prinz was driving a gray Ford F-150 truck eastbound on South Claiborne when he struck the man.

The bicyclist, whose name has not been released, was pronounced dead on the scene.

The officer was not injured and underwent a field sobriety test. The results were negative, and officers who responded to the scene did not see any signs of impairment, according to department spokesman Tyler Gamble.

Police said witnesses saw the entire incident.

Prinz has a clean disciplinary record. The Office of the Independent Police Monitor was called out to the scene Sunday night to witness the investigation. Deputy Police Monitor Simone Levine said the office’s preliminary assessment was that Prinz did not violate any traffic laws. She called the accident an “extremely tragic” situation for the witnesses and the man’s family.

The coroner’s office will conduct an autopsy, as well as blood and toxicology tests, to determine the exact cause of the man’s death.
