NEW ORLEANS – Four men, all brothers and members of a 7th Ward gang, were sentenced for their roles in a mass shooting on Mother's Day in 2013 and other gang-related crimes.

The Mother's Day shooting during a second line parade left 20 people injured. The men, according to federal prosecutors, were members of the Frenchmen/Derbigny gang, FnD, named for the intersection that was hub for the 7th Ward gang.

Travis and Akein Scott were sentenced by U.S. District Court Judge Ivan Lemelle to life in prison plus 10 years. While Shawn and Stanley Scott were each sentenced to 40 years, according to the U.S. Attorney's Office.

All had previously pleaded guilty to charges.

"Gang members sold illegal drugs, such as heroin and crack cocaine, and they committed acts of violence, including shootings. FnD members often sold drugs in the Frenchmen Meat Market, a convenience store located at the corner of Frenchmen and North Derbigny Streets. FnD members used intimidation, violence, and threats of violence to maintain the gang’s control over turf that extended from Elysian Fields Avenue, North Johnson Street, the I-10 Interstate Highway, St. Anthony Street, and North Claiborne Avenue," said a statement from the U.S. Attorney's Office.

Travis Scott, who was identified as the leader of the gang, pleaded guilty to four counts. Stanley Scott pleaded guilty to six counts, Shawn Scott pleaded guilty to five counts, and Akein Scott pleaded guilty to eight counts.

According to the U.S. Attorney's Office, Akein and Shawn pleaded guilty to the Mother's Day shooting. All four pleaded guilty to racketeering conspiracy and conspiracy to distribute heroin.
