DENVER -- Two more men connected to a violent white supremacist gang are being sought in connection with the slaying of Colorado's prisons chief, and authorities are warning officers that they are armed and dangerous.
The search comes about two weeks after prison gang member Evan Ebel — a suspect in the death of Department of Corrections chief Tom Clements on March 19 and of Nathan Leon, a pizza deliveryman, two days earlier — was killed in a shootout with Texas deputies.
While it's not clear whether the gang, the 211 Crew, is linked to the killing, the warning bulletin issued late Wednesday by the El Paso County Sheriff's Department is the first official word that other gang members may be involved.
James Lohr, 47, and Thomas Guolee, 31, aren't being called suspects in Clements' death, but their names have surfaced during the investigation, El Paso County sheriff's Lt. Jeff Kramer said. He wouldn't elaborate.
Kramer said the two are known associates of the 211 gang.
Ebel is the only suspect that investigators have named in Clements' death, but they haven't given a motive. They have said they're looking into his connection to the gang he joined while in prison, and whether that was connected to the attack.
"Investigators are looking at a lot of different possibilities. We are not stepping out and saying it's a hit or it's not a hit. We're looking at all possible motives," Kramer said Wednesday.
Investigators have said the gun Ebel used in the Texas shootout was also used to kill Clements when the prisons chief answered the front door of his home.
Sheriff's investigators said they don't know the whereabouts of Lohr and Guolee or if they are together, but Kramer said it's possible one or both of them could be headed to Nevada or Texas.
Both are wanted on warrants unrelated to Clements' death, and authorities believe they are armed and dangerous.
Guolee is a parolee who served time for intimidating a witness and giving a pawnbroker false information, among other charges, court records show. Lohr was being sought on warrants out of Las Animas County for a bail violation and a violation of a protection order, according to court records.
The 211 gang is one of the most vicious white supremacist groups operating in U.S. prisons, according to the Southern Poverty Law Center, which tracks extremist groups. It was founded in 1995 to protect white prisoners from attacks and operates only in Colorado, according to the center.
Ebel joined the 211 Crew after he entered prison in 2005 for a string of assault and menacing charges that combined for an eight-year sentence. He was supposed to spend an extra four years in prison for punching a prison officer in the face in 2006, but a clerical error led that sentence to be recorded as one to be served simultaneously with his previous sentences.
He was released on parole Jan. 28.
