Editor's note: This report has been updated to clarify the Carrollton Police Department's role in the 2012 investigation of the Aryan Brotherhood of Texas by a multi-agency task force.
FORT WORTH -- A Texas prison gang known for extreme violence and illegal drug dealings has deep roots in Tarrant County, a local drug official said Tuesday.
The Aryan Brotherhood of Texas plays a substantial role in criminal life in the county and surrounding areas, said Herschel Tebay, commander of the Tarrant County Narcotics Unit.
Investigators have explored possible connections between the group and the killing of prosecutors in Kaufman County, according to news reports. But they aren't talking about it, and regardless of whether there's any link, the Texas criminal justice system will be dealing with the Aryan group for quite a while to come.
"We probably run across them on a daily basis," Tebay said Tuesday. "If we run across white males dealing in drugs in Tarrant County, there's a good chance the Aryan Brotherhood is involved in one way or the other."
The Texas Gang Threat Assessment 2012, released this week by the Texas Department of Public Safety, notes that the gang is active in and around the Dallas-Fort Worth area. The group is among the top three most significant gangs in northeastern Texas, which includes DFW, according to the report.
In November, 34 members were indicted in federal court and arrested as a result of a multiagency investigation into the gang in North Texas and the Houston area. The Kaufman County district attorney's office, as well as the Tarrant County Sheriff's Department and the Fort Worth and Carrollton police departments were part of the task force.
Tarrant County Sheriff Dee Anderson said his department provided jail space for some of those arrested. Carrollton police said they had an officer assigned to a task force that assisted with the warrant executions.
Fort Worth police declined to comment.
Investigators in the Kaufman County killings have declined to say whether the gang is the focus of their efforts. But the killings of District Attorney Mike McLelland, his wife and assistant district attorney Mark Hasse just months after a DPS bulletin warning of potential retaliation has put the spotlight on the brotherhood.
The Aryan Brotherhood is a nationwide hate organization, first established in 1967 as a prison gang in the San Quentin penitentiary in California. The national group "maintains a working relationship with the Mexican Mafia," according to the Florida Department of Corrections.
The Texas gang was established in the early 1980s to protect white inmates in the state prison system but has since expanded to various criminal activities, authorities said.
The ABT "places its racist ideology secondary to its everyday criminal activities," the DPS report says.
Among local violent crimes blamed on those with ties to the gang are:
The killing of Fort Worth police officer Henry "Hank" Nava, 39, who was shot in the head while trying to enter a mobile home in November 2005. Stephen Lance Heard, who was affiliated with the Aryan Brotherhood, was arrested after holding a woman hostage.
The slaying of Richard Eugene Warren, 48, of Johnson County in September 2011. Police said three men used a hammer and pipe wrench to kill Warren. Two were allegedly members of the Aryan Brotherhood.
The abuse of a woman by ex-convict and Aryan Brotherhood member Ronnie Paul Kappel. He was sentenced to life in prison in May 2012 for knocking his estranged girlfriend unconscious while trying to reconcile with her at a home in Haltom City. Prosecutors said Kappel had abused women for 20 years.
The July 2012 killing of Earnest Lackey, whose boasts that he was a member of the gang cost him his life. Three Aryan Brotherhood members are accused of choking and kicking Lackey, hog-tying him with a yellow cord and beating and sexually torturing him with a soldering iron at a home in northwest Tarrant County. The motive for the slaying: The members didn't believe Lackey's claims, according to arrest warrant affidavits.
The October 2012 killing of oil executive Robert Dodson, 44, of Fort Worth. One of two men arrested and charged in the slaying is an Aryan Brotherhood member, authorities said. Dodson was robbed, hogtied and strangled with an electrical cord.
Several officials have expressed doubt that the gang could be involved in the Kaufman attacks.
Richard Roper, who served as U.S. attorney for the Northern District of Texas from 2004 to 2008, said threats on prosecutors are nothing new but have rarely been serious.
Roper said he never received threats against his life after prosecuting cases against the Aryan Brotherhood and another violent prison gang, the Texas Syndicate.
Such attacks would be counterproductive and difficult to pull off, he said.
"First, they would have to have the means and the money, and then they would have to deal with the consequences to targeting prosecutors," Roper said. "It would bring more scrutiny on them, which is something they have historically not wanted."
Angry at the system
Roper said family violence cases or domestic disputes often stir up the most intense emotions toward lawyers and judges. He pointed to the case of George Lott, who was able to sneak a 9 mm handgun into the Tarrant County Courthouse on July 1, 1992. He killed two lawyers and wounded two judges and a third lawyer. Lott was angry at the judicial system for the way his child custody case was handled.
Roper said he was threatened while prosecuting an unsuccessful 1997 plot by four Wise County Ku Klux Klan members to blow up a Mitchell Energy processing plant near Bridgeport, but nothing came of those threats.
The December retaliation warning was not the first issued to law officers in Texas.
In 2005, officers were warned that the Aryan Brotherhood of Texas was possibly planning to kill law-enforcement officers after the arrests of several high-ranking members.
"This information can be considered credible; therefore, it is advisable to approach these individuals with caution," said a federal anti-terrorism bulletin dispatched by the Anti-Terrorism Advisory Council, a division of the U.S. attorney's regional offices in Tyler.
