Diego Olmos Alcalde (Al-KAL-day), 39, was convicted Friday by a Boulder County jury in the death of Susannah Chase, a 23-year-old college student from Stamford, Conn. Olmos Alcalde received the mandatory sentence for his convictions on first-degree murder, as well as 48 years in prison for sexual assault and 24 years for kidnapping. The latter two sentences will be served concurrently to each other but after the life sentence.
Chase was attacked on a street corner in Boulder and dumped in an alley while walking home alone. Her death went unsolved for 10 years until a DNA sample connected Olmos Alcalde to the slaying.
Olmos Alcalde was arrested last year after submitting a DNA sample while in a Wyoming prison for a kidnapping conviction. His half-sister, Ona Bayers, and his ex-girlfriend, Sonci Francis, testified during the trial that days after Chase's death, Olmos Alcalde described a similar attack.
The women said that in Olmos Alcalde's story, the victim was a man he got into a fight with at a bar.
Jurors also heard from the victim in the Wyoming kidnapping case, who described how Olmos Alcalde in 2000 followed her home, then attacked her in a parking lot and tried to drag her away to a secluded area. Her family, who was nearby, came to her rescue.
Chase had left a pizzeria after an argument with her boyfriend and was attacked a block from her home on Dec. 21, 1997. She died the next day in a hospital — the same day she was supposed to fly home to Connecticut for Christmas.
