DENVER - Ryan Miller, who murdered his ex-girlfriend Andrea Roan on Dec. 16, 2011, was sentenced Monday afternoon.
Miller was sentenced to life with no possibility of parole on Monday. He was also sentenced to two years on a misdemeanor assault charge, three years on a trespassing charge and 18 additional years on two other counts.
Roan was driving in an alley behind her Denver home when she was shot in the head and crashed her car into a nearby garage.
Roan had ended a short relationship with Miller, and had tried to get a protective order against him before the murder. Miller had showed up outside of Roan's apartment, forcing his way inside. Neighbors heard her screams and came to her rescue.
The man who prosecutors say drove Miller to and from Roan's apartment the morning of the shooting pleaded guilty to second-degree murder in January.
Andrea Roan, who died at 27, was a fifth-grade teacher at Alsup Elementary in Commerce City.
