Oregon State Police (OSP), with the assistance of the Columbia County Sheriff's Office and Washington County District Attorney's Office, arrested a Beaverton-area man Friday afternoon on sex abuse and sodomy charges following an investigation into a report of alleged crimes that occurred in the late 1990's into the early 2000's involving a then-juvenile age girl. OSP is attempting to confirm if there were other possible victims involving the suspect.
WILLIAM MAYO DUNLOP, age 68, was arrested September 9, 2011 at his residence in the 17000 block of Pike Street in Beaverton on charges of Sex Abuse in the First Degree and Sodomy in the First Degree. DUNLOP was lodged in the Washington County Jail with bail set at $250,000.
The victim, who is now 22 years of age, recently contacted Columbia County Sheriff's Office to report alleged sex abuse by DUNLOP during the late 1990's into 2002. Columbia County Sheriff's Office requested investigative assistance by OSP detectives and Washington County District Attorney's Office.
DUNLOP has worked in the past as a school bus driver and in the clown entertaining business since the 1970's. Over the years the clown entertaining business has been located in the St. Helens, St. Johns area of Portland, and Beaverton areas. The alleged crimes for which DUNLOP was arrested did not occur in a work-related environment but he did meet the victim while working as a school bus driver in Columbia County.
OSP Detective Aaron Jackson is the lead investigator in this case and is investigating the possibility that there may have been other victims who had contact with DUNLOP since the 1990s.
Anyone with information related to this investigation is asked to call Detective Jackson at (503) 731-3020 ext. 269.
