Woman charged with buying gun used in Colorado prison's killing From Ed Lavandera, CNN March 28, 2013 -- Updated 0728 GMT (1528 HKT) (CNN) -- A 22-year-old woman is accused of buying the weapon used to kill Colorado prison chief Tom Clements last week and funneling the weapon to the alleged gunman. The Colorado Bureau of Investigation said Stevie Marie Vigil of Commerce City, Colorado, was arrested Wednesday night. Authorities say she made a "straw purchase" from a weapons dealer and transferred the weapon to Evan Ebel, a convicted felon who could not purchase his own firearm. Clements was shot to death at his home outside Colorado Springs on March 19.
