A Colorado child molester was arrested in Tucson Tuesday by the U.S. Marshals Service.

Juan Carlos Sanchez, 40, was a fugitive and one of Colorado’s “Top 100 Most Wanted Sex Offenders,” Deputy U.S. Marshal Daniel Leyva, said in a news release. Sanchez was arrested on a warrant out of El Paso County District Court in Colorado.

“In September 2005, Sanchez was convicted of sexual assault on a child after he put a muscle relaxer in the drink of a 12 year old girl and then sexually assaulted her,” Leyva said.

As a result of his conviction, Sanchez is required to register as a sex offender. In 2007, Sanchez was suspected of drugging and sexually assaulting a 19-year-old Colorado woman, Leyva said.

“Investigators in Colorado attempted to interview Sanchez, however, he fled the state and the case became cold. In 2011, the case was reopened and warrants were issued for the alleged sexual assault as well as failure to register as a sex offender,” Leyva said.

Recently, the Marshals Service received information that Sanchez was in Tucson. Deputies set up surveillance on a house in the area of North Oracle and West Roger roads. They followed Sanchez when he left the house with two women and drove to a fast food restaurant at North Campbell Avenue and East Fort Lowell Road and arrested him.

He was booked into the Pima County jail pending extradition to Colorado.
