A federal court judge was set to sentence Stevie Marie Anne Vigil, 23, who pleaded guilty to buying a handgun used in the killing last year of prisons chief Tom Clements. Vigil faces a maximum of 10 years in prison.
Federal prosecutors say paroled prison gang member Evan Ebel also used the gun to kill Nathan Leon, a Denver computer technician and pizza deliveryman, and wound a sheriff's deputy in Texas, where Ebel fled. Ebel was killed in a shootout with Texas authorities.
The judge has allowed Clements' widow, Lisa Clements, Leon's relatives and the Texas deputy to testify Monday about their losses.
Clements, 58, was fatally shot when he answered the door of his Monument home on March 19.
Authorities have said Ebel, 28, killed Leon two days before by luring him to a remote intersection by ordering a pizza. He then used Leon's Domino's Pizza uniform to disguise himself when he appeared at Clements' home.
With Ebel dead, Vigil has so far been the only person to face a criminal charge related to the prison chief's killing. Although El Paso County sheriff's investigators have not definitively named Ebel the gunman, they have linked the 9 mm Smith & Wesson handgun Vigil purchased for Ebel to both killings.
Defense attorneys have argued that Vigil was unaware of Ebel's criminal intentions and did not conspire with him.
Prosecutors say Vigil, a childhood friend of Ebel's, knew he was a convicted felon and could not buy the firearm himself. She then lied to investigators, saying she bought the gun for herself for protection.
"Vigil put a murder weapon in the hands of a murderer," prosecutors wrote in recent court filings. "While Evan Ebel is ultimately responsible for the shootings, Vigil enabled these horrific crimes by giving Ebel the tool he needed. Lives were lost and families were devastated as a result."
Ebel was convicted of several crimes in Colorado dating to 2003, including assaulting a prison guard in 2008. He was released on parole Jan. 28, 2013—four years early—because of a clerical error. He then removed the ankle monitoring bracelet he was required to wear.
