A Colchester man was arraigned Wednesday on multiple charges related to the fatal shooting of a rival drug dealer last year.

The United States Attorney’s Office says Dominique Troupe, 36, was a primary source of crack cocaine sold from a house in Swanton, and to protect his operation, he planned an armed robbery of a rival, Elijah Oliver.

Authorities say Oliver was shot and killed on February 2, 2022, during the attempted robbery. Troupe, who is already in custody on previous charges, has been charged with conspiracy to distribute crack, using a gun in a robbery and two other counts.

He faces a minimum sentence of 15 years if convicted.
