CONCORD - A man wanted for failing to appear at a court hearing on charges of forged or false prescriptions is this week's U.S. Marshals Services' Fugitive of the Week.

Shaun Michael Ellis, 51, also known as Normand Ellis and Shawn Ellis, is wanted by the Sullivan County Sheriff's Office. The warrant was issued on Jan. 20, 2012.

His last known address was in Unity, and authorities believe he could still be in that area or possibly in the Cape Cod area, where he once lived.

Ellis is described as a white man, 5-foot-11, weighing 215 pounds with gray or blond hair with a medium skin tone. He has tattoos on his arms, calves and chest.

Authorities caution Ellis has violent tendencies, is considered armed and dangerous and no one should attempt to apprehend him. Instead, report any information to the local U.S Marshals Services at 225-1632 in Concord or call 1-877-WANTED-2.
