Original story: A New Orleans police officer was killed today while transporting a suspect in a police vehicle. New Orleans police Superintendent Michael Harrison confirmed the officer killed is 46-year-old Daryle Holloway, a 22-year veteran of the department.

According to police spokesman Tyler Gamble, Holloway died at 9 a.m. at a nearby hospital about 30 minutes after he was shot in the head by the suspect, causing the car to hit a utility pole at an intersection before coming to a stop. Power went down in nearby areas, drawing dozens of police officers to the scene.

“He was on duty,” said Harrison, according to local newspaper The Times-Picayune. “He was transporting a prisoner who had been arrested on a previous shift.” The suspect, 33-year-old Travis Boys, is at large. Louisiana State Police and a SWAT team have reportedly joined the New Orleans Police Department in a city-wide manhunt for Boys, who was previously arrested on aggravated assault charges. Police say Boys fled the scene on foot.

“Today is an extremely sad day for the police department and a sad day for the city of New Orleans,” Harrison said in a statement.

Harrison said that Boys was handcuffed in the back seat of the police cruiser but was able to free his hands from behind him. While the vehicle was in motion, Boys then made his way through a small opening in the caging of the car that separates the front and back of the car and grabbed hold of Holloway’s gun. Officer Holloway reportedly put up a fight before being shot in the head.

“He will pay for what he did,” said Harrison, a personal friend of the slain officer.
