Man accused of repeated sex assaults on teen girl

Arrest mugshot of Jeffery Jansen

District Attorney Pete Hautzinger on Tuesday said a man accused of sexually assaulting a girl three times within weeks will be charged as a habitual criminal.

Jeffrey Jay Jansen, 45, of Grand Junction was ordered by County Court Judge Bruce Raaum to be held on $150,000 bond following his arrest Monday evening on multiple charges, including three counts of sexual assault on a child.

Jansen was arrested hours after a Mesa County Sheriff’s investigator received a referral from a caseworker with the Mesa County Department of Human Services, involving allegations from a 16-year-old girl.

The girl told authorities she had been sexually assaulted three times between late February and March 13 while at a home in Clifton with Jansen, according to an arrest affidavit.

She claimed she was given alcohol by Jansen on one occasion, and was later forced to perform several sex acts.

“(Girl) said Jeffrey kept telling her not to tell anyone,” the affidavit said.

On Monday, the girl called Jansen on his cell phone as investigators listened in on the call, according to the affidavit.

“Jeffrey encouraged her not to tell anyone, pointing out how much trouble he would be in if she told,” the affidavit said. “Jeffrey told (girl) during this conversation that he felt guilty about
what he had done.”

Hautzinger told the judge on Tuesday he’ll press for a habitual criminal conviction because of Jansen’s three prior felonies. A check of Colorado Bureau of Investigation records show he’s been arrested at least three times since 1982 on multiple charges, including menacing, burglary and assault.

Jansen will be formally charged in District Judge Brian Flynn’s courtroom on Tuesday.
