SIOUX FALLS, S.D. (Dakota News Now) - Police say 17-year-old Devon Moses Montileaux is in police custody in connection with the fatal shooting of a Sioux Falls teen earlier this month.

Montileaux is charged with second-degree murder and first-degree manslaughter for his role in the shooting death of 16-year-old Ephraim Duolo Shulue, police say.

On December 9, police say Shulue was killed during an attempted drug rip. Police say 16-year-old Ali Khalifa Ahmed and 17-year-old Sembel Sale was with Shulue for a marijuana deal. Shulue and Sale entered a car with Montileaux and another person to sell marijuana but attempted to rob them at gunpoint.

Police say an argument broke out leading to Shulue being shot. Investigators believe the round that struck Shulue came from a firearm in Montileaux’s possession at the time.

While Ahmed and Sale did not fire the bullet that killed Shulue, Lt. Terrance Matia said they are still being charged with murder because they were involved in the crime that resulted in his death.
