A councilman of the City of Green River has been arrested based on allegations that he repeatedly sexually abused a young boy.

Allan Wilson is charged with second-degree sexual abuse of a minor in Sweetwater County, as well as first-degree sexual abuse of a minor in Lincoln County. He could face up to 70 years imprisonment if convicted on both counts.

Court documents say the same boy -- a family member -- was victimized in each county. The charges specify that the alleged abuse occurred when the victim was as young as seven years old.

Wilson allegedly abused the victim during a 2011 trip to property near Commissary Ridge, in the Kemmerer area. Wilson and the victim stayed in a camper during such trips.

The Sweetwater County charges stem from an alleged incident in which Wilson reportedly molested the victim while driving through Green River in a silver pickup truck in 2013.

The victim reported the alleged abuse after his behavior changed drastically, prompting his parents to ask if someone had molested him.

The Sweetwater County Detention Center on Thursday confirmed Wilson was in custody, but declined to release further information.
