A man was killed and a Louisiana State Police trooper was shot in the arm Sunday during an auto theft investigation in New Orleans.

New Orleans Superintendent of Police Michael Harrison said during a news conference Sunday that state troopers attempted a traffic stop in the 7th Ward at about 3:30 p.m. of a vehicle that was believed to be reported stolen. Three suspects emerged from the vehicle and one began firing at the troopers, striking one in the elbow, Harrison said.

The suspects then ran from the scene, hiding on nearby blocks in the area. Within minutes, New Orleans and Louisiana State police officers arrived on the scene and began to search for the suspects.

When authorities located one of the suspects, he began to fire at police who returned fire, striking the suspect, Harrison said. He died at the scene.

Details were not immediately available about the man who was killed.

Police are still searching for the two other suspects, described as black males, Harrison said.

"This is still a very active scene," he said.

SWAT and the FBI were also assisting in the investigation.

Detectives were reviewing video footage from in-car cameras from both agencies as well as NOPD body cameras that were activated at the scene, Harrison said.

The state trooper is listed in stable condition, Louisiana State Police Col. Mike Edmonson said at the news conference Sunday. Edmonson did not identify the trooper or his race.

Edmonson said almost 300 stolen vehicles have been found outside the French Quarter surrounding area in the past year and a half with 60 being found so far this year.

"It's important for us on those stolen vehicles cause from those we've found wanted persons, we've found drugs, we've found weapons," Edmonson said.
