LAFAYETTE — The main defendant in a loosely organized Lafayette gang referred to as the Truman Cartel pleaded guilty in federal court Thursday to a drug conspiracy charge.

Martin Victor Jr., 52, also known as “Steak,” was one of 13 people indicted in December 2009 on drug conspiracy charges involving the distribution of powder and crack cocaine in and around Lafayette.

The case was investigated by the South Central Louisiana Safe Streets Gang Task Force, a multi-agency group of federal, state and local officials.

At the time of the arrests, Lafayette Police Chief Jim Craft said those involved had a combined 191 prior arrests.

Victor pleaded guilty Wednesday to one count of conspiracy to distribute and possess with intent to distribute cocaine base and cocaine.

He faces a prison sentence of 20 years to life, according to the terms of his plea.

Victor also agreed in court to forfeit to the government any ownership and interest he had in about $54,000 in cash that was seized during the investigation.

He also agreed to forfeit a 1997 Suzuki motorcycle, a 2000 Harley Davidson motorcycle, a shotgun, a residential lot and structure at 124 Rosewood Ave. and several lots in the North College Heights Subdivision.

Two other defendants, Justin James Thibeaux and Derrick James Simpson, also pleaded guilty to drug conspiracy charges in court Wednesday.

Two defendants, Amelia Victor and Leonard Morrison, have not pleaded guilty in the case, according to court filings.
