A Parker man was sentenced Monday to 24 years to life in prison for repeatedly sexually assaulting his intellectually disabled stepdaughter over a period of several years.

George Robert Gipson, 65, was convicted following a jury trial of six counts of sexual assault on an at-risk person and four counts of unlawful sexual contact of an at-risk person, according to a news release from the 23rd Judicial District Attorney’s Office.

According to prosecutors, the victim, who has intellectual and cognitive disabilities, disclosed the abuse to her mother, who reported it to a case worker at a care facility for adults with disabilities. The victim told investigators that Gipson sexually assaulted her numerous times beginning in 2022.

Authorities said the victim also reported that Gipson showed her pornography on his phone before assaulting her at their Parker home while her mother was out of town.

An investigation by the Parker Police Department led to Gipson’s arrest in 2024. During the trial, Gipson denied committing the crimes. 

Chief Deputy District Attorney Danielle Jaramillo said the victim’s willingness to come forward was instrumental in securing the conviction.

“This sexual predator took advantage of an at-risk person, thinking he would never be caught,” Jaramillo said in the release.

Senior Deputy District Attorney Lauren Raible said the sentence reflects the seriousness of crimes committed against vulnerable victims.

“This case is about the abuse of trust and power against someone who was especially vulnerable,” Raible said.

Gipson will serve his sentence in the Colorado Department of Corrections.
