The Boulder District Attorney’s human trafficking unit arrested three men allegedly involved in a sting aimed at drawing suspects into a fake commercial sex operation promising children between 12 and 14-years-old.

On Thursday and Friday, authorities arrested Jesse Spink, 39, Diego Lopez-Jiminez, 28, and Christian Quinones, 36, according to a news release.

The three were arrested after arriving at a location where they responded to advertised solicitations for sex with minors, according to the Boulder County District Attorney’s office.

The men face charges of criminal attempt to commit human trafficking of a minor for sexual servitude and criminal attempt to commit sexual assault on a child, both felonies.

The arrests were conducted following an operation “focused on identifying and arresting adults who responded to commercial sex advertisements pertaining to illegal activities/violations with minor children, ages 12 and 14,” Boulder County District Attorney’s Office officials said in the release.

The law enforcement agencies involved in the operation included U.S. Homeland Security, Colorado Bureau of Investigation, Longmont Police Department, Aurora Police Department and the Boulder County Computer Forensics Lab.

“The purpose of this Human Trafficking Operation was to stop people who were willing, and attempted, to exploit children,” District Attorney Michael Dougherty said in the release.

“These arrests are a direct result of outstanding efforts and teamwork of the investigators and our partners,” he said. “We will continue to work tirelessly to ensure the safety of our youth and fighting for the right results in these cases.”
