Estabrooks was convicted on four counts of indecent assault in 1999 and served jail time before his death in 2005. Mayor Mel Norton wants the public to know that after receiving the complaint, the City took immediate action.
He says shortly after receiving the complaint the City contacted an arms-length investigative firm, Investigative Solutions Network, to initiate an investigation.
Dave Perry of Investigative Solutions says sexual abuse investigations are never closed permanently.
He says if they finish their work in a couple of weeks or a couple of months and someone came forward in year they would have to listen to that person.
ISN will examine Estabrooks former work places to see where the alleged abuse took place.
The City is offering to provide counselling to any victims that come forward.
