Kramer said Lohr and Guolee are known associates of the 211 Crew. That's the same gang whose members included Evan Ebel, who is a suspect in the death of Clements on March 19 and a pizza deliveryman two days earlier.
Ebel was killed in a shootout with Texas authorities after the deaths. Investigators have said the gun Ebel used in the shootout was also used to kill Clements when the prisons chief answered the front door of his home.
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.
Sheriff's investigators 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. They are believed to be 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.
Clements, born in St. Louis, worked for 31 years in the Missouri Department of Corrections, both in prison and as a parole officer, before he was hired in Colorado.
