The Weld County Sheriff’s Office was among the first law enforcement agencies in the State to join the US Marshals Adam Walsh Task Force. The Task Force assists any agency in the State of Colorado with sex offender compliance checks, sex offender warrant operations, and investigates sex offenders who cross state lines without complying with sex offender registration laws. Suspected violations are forwarded to the US Attorney for federal prosecution in violation of the Adam Walsh Child Protection and Safety Act enacted July 27, 2006.
The Adam Walsh Child Protection and Safety Act was signed on the 25th anniversary of the abduction of Adam Walsh from a shopping mall in Florida. Adam Walsh was found murdered 16 days after his abduction in 1981, and the perpetrator was not named until December 16, 2008, when the Hollywood, Florida police department announced that they had evidence that Ottis Toole was the killer. Adam Walsh's father is John Walsh, host of the television series America's Most Wanted. John Walsh, also founder of the National Center for Missing and Exploited Children (NCMEC), was joined by other children's advocates to mount an aggressive campaign to get the bill passed into law.
WCSO deputies on the Task Force are deputized as Special Deputy US Marshals.
