DENVER — A man accused of sexually assaulting a pregnant woman in 1999 was sentenced Friday to prison, the Denver District Attorney’s Office said.

Roberto Valenzuela, 62, was charged in September 2016 with kidnapping and sexual assault.

He pleaded guilty in August to second-degree assault-serious bodily injury and first-degree attempted sexual assault.

He was sentenced in Denver District Court on Friday afternoon to 16 years in prison, three years mandatory parole for the assault conviction, and three years in prison and two years mandatory parole for the attempted assault conviction.

The sentences will run concurrently.

In November 1999, Valenzuela offered a ride to the victim. He drove her to a church parking lot, hit her in the face and sexually assaulted her in his car, prosecutors said.

He then took her to a second location where he committed a second sexual assault, the district attorney’s office said.

The victim escaped when Valenzuela stopped at a stop sign.

The victim had been out walking that night after having a fight with her boyfriend. She was five months pregnant at the time of the assault.

Valenzuela was identified as a suspect through the work of Denver’s Cold Case Project, and was arrested in September 2016.
