CORNWALL, Ont. - A former Cornwall, Ont., police officer who cleared the way for the Project Truth inquiry is expected to begin his testimony today.

Perry Dunlop's independent investigations led to allegations of children being sexually assaulted by prominent community members.

After a lengthy investigation, police laid 114 charges against 15 high-profile men, including doctors, lawyers and priests. But police later said they found no evidence of a pedophile ring and the Project Truth inquiry began in February 2006 to probe the investigation.

Dunlop's name has often surfaced at the inquiry from witnesses testifying about abuse they allegedly suffered from authority figures.

Many said they had some contact with Dunlop and his wife as Dunlop conducted an investigation into the allegations. Some have suggested the former cop tried to embellish and even fabricate evidence.

Dunlop was charged under the Police Services Act but later exonerated for disclosing evidence of a payoff by the local Roman Catholic diocese to a sexual abuse victim in exchange for silence.
