New Orleans homicide detectives continue to receive numerous tips about the second gunman responsible for last week’s Bourbon Street shooting but so far have not been able to pin down his identity, Police Superintendent Ronal Serpas said Thursday.

While the tips so far have not borne fruit, investigators are reviewing about 40 hours of surveillance video they have collected since the June 29 shooting in an effort to pinpoint the other suspect.

“I have every confidence we will identify the second shooter,” Serpas said.

He made the comments during a meeting with state troopers as they prepared to begin another day of temporary foot and vehicle patrols in the French Quarter and Faubourg Marigny.

The troopers — some from Troop B in Kenner, others from Troop A near Baton Rouge, Troop C in the River Parishes and Troop L in St. Tammany Parish — will be in the city until Labor Day in response to a plea from Mayor Mitch Landrieu for additional law enforcement manpower after the shooting.

In addition to the two neighborhoods popular with tourists, Serpas said, the troopers also will patrol in Treme, Bywater, parts of Uptown and other areas based on computerized crime data.

“Where they need us is where we’ll go,” State Police Superintendent Col. Mike Edmonson has said.

While the mayor asked for 100 troopers on a long-term basis, Edmonson said he could not fulfill that request without affecting other parts of the state.

New Orleans police have identified Trung T. Le, 20, of Belle Chasse, as one of the suspected gunmen in the shooting that killed one and wounded nine others. He was arrested last week near Gulfport, Mississippi, and remains locked up in the Harrison County jail while fighting extradition to Louisiana.

Serpas has said police believe the second gunman ran down Bourbon Street to Esplanade Avenue, then in the direction of North Rampart Street.

While detectives have nearly two days’ worth of video in their possession, there could be critical video they do not yet have, Serpas said.

“This is a final plea to the public. The suspects were running fast and far” after the shooting, Serpas said. “Take a look at your video.”

Crimestoppers has increased to $5,000 its reward for any information that leads to an arrest of the second gunman. Tips can be phoned in by calling (504) 822-1111. Callers can remain anonymous.
