The late Estabrooks, a former sergeant, was found guilty in September 1999 of indecent assault against four children, in cases dating back to the 1950s. The abuse included fondling and oral sex.
In 1975, Estabrooks had admitted to sexually abusing children, but he wasn't charged or fired.
Estabrooks died in 2005.
The City of Saint John hired Toronto-based Investigative Solutions Network Inc. in August 2012 for $100,000 to look into at least one other historical complaint against Estabrooks.
In November, the city revealed there were 12 new alleged victims and allocated another $100,000 to probe complaints.
