Onetime LSU defensive back Troy Hankton and a cousin, Nakia Hankton, pleaded guilty in federal court on Thursday, admitting roles in a drug-dealing conspiracy allegedly headed by their notorious cousin, accused New Orleans crime leader Telly Hankton.

In court documents supporting his guilty plea to a firearms conspiracy count, Troy Hankton, 31, admitted dealing drugs almost daily around the Hankton turf on Josephine Street in Central City.

He also admitted firing into a vehicle at Clara and Fourth streets on April 12, 2007, with “another individual.” The other individual, according to the 24-count federal indictment, was Telly Hankton.

Inside the vehicle were Karim Peters, who was shot, along with Darnell Stewart and Jessie “TuTu” Reed.

Eight months after that shooting, an older cousin, George “Cup” Hankton, was killed; Stewart and Reed were suspected but never charged in that crime.

Five months after that, Telly Hankton gunned down Stewart on South Claiborne Avenue, a brazen execution-style murder for which he is now serving life in prison.

And a year after Stewart’s killing, while Telly Hankton was free on $1 million bond, he and two others — accused hit man Walter Porter and Kevin Jackson — are alleged to have killed Reed on Terpsichore Street.

Porter and Jackson are among nine remaining defendants slated for trial in June in the high-profile federal racketeering case, which alleges a drug conspiracy dating back decades that was led by Telly Hankton, 39, whom city officials once described as the most dangerous criminal in New Orleans.

Four of the named defendants — Troy and Nakia Hankton and Derrick and Terrell Smothers — recently agreed to plead guilty in the case.

In his guilty plea Thursday, Nakia Hankton, 39, admitted to the main racketeering charge and a drug conspiracy count. He acknowledged running large quantities of cocaine from Houston and dealing various drugs on Central City streets dating back at least to 1996.

Nakia Hankton faces 10 years to life in prison. Troy Hankton faces a maximum 20-year sentence. Both are scheduled for sentencing Sept. 14.

Troy Hankton is a former football standout and honor student at Walter L. Cohen High School, where he graduated in 2002. He signed to play at LSU but stopped playing football before his sophomore year due to a medical hardship, according to a 2003 Times-Picayune story.

Derrick Smothers and Terrell Smothers are scheduled to enter their guilty pleas next week.

None of the four were accused in a host of murders contained in the federal indictment.
