Louisiana prosecutors have ruled out any criminal charges in the death of a south Louisiana man who was fatally shot while handcuffed in the back of a patrol car.

A statement Friday from the 16th Judicial District Attorney's Office says there is "insufficient credible evidence" to conclude that 22-year-old Victor White III did not shoot himself while he was in the custody of the Iberia Parish Sheriff's Office in March 2014.

A coroner ruled White shot himself in the chest despite being handcuffed behind his back following his drug-related arrest.

The Justice Department announced in December that no federal charges would be filed in connection with White's death.

Carol Powell Lexing is an attorney for White's family. Powell said family members are disappointed but not surprised by the district attorney's decision.
