UPDATE: The Iberville Parish Sheriff's Office said Sunday night's shooting that left 17-year-old DeShannon Woods dead in Plaquemine was a case of self-defense.

Authorities say a group of six or seven people were playing dice on a front porch Sunday night when two armed robbers approached them. The two then demanded the group's money. 

The sheriff's office said a 16-year-old who was part of the dice game pulled out a gun and fatally shot one of the robbers. Deputies say the teen is not being charged with the death, however, he will be charged for being a juvenile in possession of a weapon.

Two others, 20-year-old Reginald Dorsey and 17-year-old DeShannon Johnson, have been arrested by authorities. The sheriff says the robbery was Dorsey's idea, while Johnson is accused of hiding a weapon used in the crime. 

Investigators say they found the robbers' weapons buried in Addis.

Dorsey is charged with first-degree murder and armed robbery. Johnson is charged with obstruction of justice and accessory after the fact to armed robbery.
