The victim was thrown from her bike and died at the scene due to blunt force trauma to the head. Her son was taken to the hospital where he was treated for minor injuries.
Trujillo was driving under the influence of multiple prescription drugs including Oxycontin, Vicodin, Xanax and Soma. He also had a blood alcohol level of .11 percent.
Trujillo was convicted in June of second-degree murder.
The victim's family members gave emotional victim impact statements to the court during the trial.
"At the time of Cathy's death, we had been married for approximately 16 years. We had only one son, Samuel, who suffers from autism. Cathy lived and breathed for our son," said the victim's husband, Ben Busse. "Now I am faced with an uncertain future about what will happen to Sam in the event of my death. Who will take care of him?"
Also during the trial, it was shown that Trujillo frequented four different pharmacies to obtain between 120 and 180 Vicodin pills as well as between 60 and 120 Oxycontin pills every month.
