GOLDEN, Colo. (Mar. 9, 2026) – Today, Rubel Tim Martinez was sentenced to an indeterminate term of imprisonment of at least 18 years and up to life in the Department of Corrections. The Court also imposed an indeterminate period of parole of at least 20 years and up to life, pursuant to C.R.S. 18-1.3-1004(2)(a).
On January 19, 2026, following a four-day trial, the jury deliberated for just under three hours before returning its guilty verdict.
The jury found that Martinez committed repeated sexual contact against the same victim while employed as a Campus Security Supervisor. The assaults occurred during and after school hours, both on and off school grounds, while the victim was a junior and senior at Lakewood High School from 2014 to 2016.
At today’s sentencing hearing, Deputy District Attorney Kelsey Einhorn emphasized the defendant’s abuse of his position of trust.
“Everyone puts their trust in the school system. Parents send their children to school and entrust teachers, principals, and security guards to watch over them,” Einhorn said. “His job was to ensure the safety of students, to protect kids. Instead of using that position of trust to do that, the defendant manipulated a sixteen-year-old into sexual acts.”
Einhorn also commended the victim for her bravery, describing the “incredible amount of strength” she demonstrated throughout the case.
“Not only in coming forward and telling her story, but the strength and bravery she has shown from when I first met her, when this case was filed in August 2024, until now, March 2026, has been absolutely remarkable to witness,” Einhorn said.
Einhorn added that from the beginning, the victim’s only motivation was for others to know what the defendant had done to her. “She finally got to speak her truth,” Einhorn said.
First Judicial District Court Judge Christopher Rhamey said the case involved “extraordinary aggravation,” noting that the victim was a vulnerable child who was targeted during an impressionable time in her life.
Rhamey emphasized that the crime occurred in a “location where all children need to be safe, and sadly, that’s not the case anymore. It’s schools.”
He added that the defendant engaged in “aggravated grooming behavior” and preyed on a child who was in a very difficult situation.
Martinez’s sentence includes an indeterminate term of imprisonment of at least 18 years and up to life in the Department of Corrections, as well as an indeterminate period of parole of at least 20 years and up to life pursuant to C.R.S. 18-1.3-1004(2)(a), just six years shy of the statutory maximum sentence.
The victim provided the following statement for public release:
“While this was something that happened a decade ago, this is still something that is happening every day to our children. It is disappointing and truly unacceptable. To those who survived such trauma, I urge you to share your story and not let it eat you alive. We are not alone, and it was not our fault. I am elated and ever grateful for the justice that was served, as justice for an Indigenous woman is not often seen nor received, and now more than ever, I am inspired to continue to help others in the ways I have received help throughout this process.”
