The man convicted of beating to death 23-year-old University of Colorado student Susannah Chase on a Boulder street nearly a dozen years ago has been sent to Sterling Correctional Facility to serve out his life sentence.
Diego Olmos Alcalde, 40, was assigned to the 2,500-bed prison 140 miles east of Boulder earlier this week, said Colorado Department of Corrections spokeswoman Katherine Sanguinetti.
A Boulder jury found Alcalde guilty of first-degree murder, first-degree sexual assault and second-degree kidnapping on June 26, after a three-week trial.
Three days later, he was sentenced to life in prison with no chance of parole.
Alcalde beat Chase over the head with a baseball bat near her home at 18th and Spruce streets during the early morning hours of Dec. 21, 1997.
He then raped her and drove her to an alley about a block away, where he dumped her body. Chase died the next day.
Police were unable to identify any suspects in the case until 2008, when genetic material found at the crime scene that had been submitted to a criminal database years earlier matched a DNA sample Alcalde had to give when he was finishing a prison sentence in Wyoming for an unrelated crime.
Alcalde was arrested at his mother's house in Aurora and charged with Chase's murder.
Last year, the Boulder County District Attorney's Office decided not to seek the death penalty for Alcalde.
The conviction in June put to rest one of Boulder's most vexing unsolved murder cases.
