WASHINGTON--Thirty-four alleged members of the prison-based Aryan Brotherhood of Texas (ABT) gang, including four of its most senior leaders, were indicted by a federal grand jury in Houston, according to the U.S. Attorney's Office.

They are charged with conspiring to participate in racketeering enterprise, state federal authorities.

Alleged members of the ABT are also charged with involvement in three murders, multiple attempted murders, kidnappings, assaults, and conspiracy to distribute methamphetamine and cocaine.

The federal indictment was unsealed on Friday.

According to court documents, the ABT has a detailed and uniform organizational structure, with territory divided into five regions, each run by a "general." The superseding indictment charges four generals: Terry Ross Blake, 55, aka "Big Terry"; Larry Max Bryan, 51, aka "Slick"; William David Maynard, 42, aka "Baby Huey"; and Charles Lee Roberts, 68, aka "Jive," with conspiracy to participate in the racketeering activities of the ABT, among other charges.

PHILADELPHIA--Darwin D. Dieter, 53, of Kempton, Pennsylvania, allegedly stole more than $500,000 in checks that were issued by his insurance company that were intended for payment of his wife's dialysis treatments, federal officials state.

An indictment was unsealed last week in connection with a health care fraud scheme, according to the U.S. Attorney's Office.

Dieter, a former employee of a direct mail company located in Hamburg, Pennsylvania, kept the checks and laundered the proceeds from December 2010 to July 2011.

Dieter was arrested by Friday by the FBI, according to federal authorities.
