David Perry, of Toronto-based Investigative Solutions Network, says the city received a sexual assault complaint involving Sgt. Ken Estabrooks earlier this year that dates back to the 1970s.
Estabrooks died in 2005.
He was convicted in 1999 of indecent assault against four young people between 1957 and 1982 and received a six-year prison sentence.
