LAFAYETTE — Four men arrested in a December 2009 drug investigation on Helen Street were sentenced this week in 15th Judicial District Court in Lafayette, an official said.

Raytell L. Williams, Clifton Carmouche, Issac Andrus and John Trahan all received sentences ranging from 17.5 to 30 years for distribution of cocaine, according to a news release issued Thursday.

The men were all targeted in a raid and subsequent crack down aimed at curbing criminal activity in an area known as “New Jack.”

The raid was three-months in the making and involved a contingent of local, state and federal authorities. At the time of the raid, officials said the area was a hotspot for purchasing crack cocaine and other drugs.

Assistant District Attorney Mark T. Garber acknowledged the assistance of various law enforcement agencies involved in the case, “which enabled the Office of the District Attorney to successfully prosecute these drug dealers and to remove them from our society.”

Williams, 33, was sentenced to serve 30 years at hard labor.

Carmouche, 39, was sentenced to serve 20 years at hard labor.

Andrus, 36, was sentenced to serve 17.5 years at hard labor.

Trahan, 47, was sentenced to serve 25 years at hard labor.
