A Jefferson County jury found a former school security guard and pastor guilty of sexual assault on a child by a person in a position of trust.

The jury deliberated on Friday after a four-day trial, eventually finding that 68-year-old Rubel “Tim” Martinez was guilty of the felony charge that stemmed back to 2016, according to a news release from the First Judicial District Attorney’s Office.

Police arrested Martinez on Aug. 16, 2024 after receiving a report from a former Lakewood High School student that Martinez allegedly assaulted her on and off the campus between 2014 and 2016, according to a previous news release from Lakewood police.

Martinez worked as a “Campus Security Supervisor” at Lakewood High School and at Jefferson Jr./Sr. High School between 2006 and 2022. He also ran an after-school clown club at Lakewood High School and worked as a pastor at Breakthrough Ministries in Weld County.

Martinez was out on bond until Friday, but has since been arrested and will be held until his sentencing on March 9, according to the release. He faces up to 12 years in prison for the Class 3 felony.

The conviction came just a week after 38-year-old James Michael Chevrier — a former Jeffco Public Schools psychologist — was found guilty of the same charge, along with multiple drug charges.

Martinez’s case was one of the seven arrests or investigations regarding sexual assault on a child or related misconduct in Jefferson County Public Schools since the end of 2023 until the beginning of January.

The most recent was the arrest of 39-year-old Patricio Alejandro Illanes, a former Arvada High School teacher, last week for allegedly filming sexual exploitation videos of juveniles and distributing them on various websites.
