NEW ORLEANS (AP) — A spokesman for the U.S. Justice Department says the agency will not pursue a criminal investigation involving an FBI agent who shot and killed a New Orleans man during an undercover drug sting last summer.

Dena Iverson tells Times Picayune the Civil Rights Division reviewed the information collected by the FBI regarding the shooting and declined to open a criminal investigation.

The decision comes more than three months after Orleans Parish District Attorney Leon Cannizzaro's office declined to pursue charges against the agent, who fatally shot 37-year-old Allen Desdunes on July 30. He referred the case to federal prosecutors on jurisdictional grounds.

The shooting occurred in the back of a Motel 6 parking lot during what the FBI has said was a drug-related surveillance operation.
