The Colorado Bureau of Investigations arrested a woman they allege acquired the firearm used to murder prison chief Tom Clements in front of his home on Mar. 19.
Authorities said Stevie Marie Vigil, 22, bought a firearm from a licensed dealer and gave it to Evan Ebel, 28, who as a felon could not legally possess a firearm.
Ebel is accused of shooting the chief of the Department of Corrections as well as Nathan Leon, a pizza delivery man. After a high speed chase, the parolee was killed in a police shootout Friday.
Vigil, of Commerce City, Col., is charged with a felony count of unlawful purchase of a firearm and is being held on bail $25,000.
The Daily Mail reported that Vigil, in an online profile, described herself as an aspiring plus-size model.
The records associated with Vigil's arrest are sealed. As of now, it is unclear how she and Ebel were connected.
Ebel was parolled Jan. 28 after serving four years, the full sentence, for punching a prison guard in 2008.
Many of his acquaintances claim Ebel had always been a troubled young man. Colorado Gov. John Hickenlooper had been a longtime friend of his family and said that Evan "had a bad streak."Police are investigating whether the murder of Clements was Ebel's doing alone or he was put up to it by prison gang members.
After he was shot by law enforcement in Decatur, TX, authorities found bomb-making materials in his car.
