Undercover officer says Mr. Big sting did not prey on David Caissie's vulnerabilities

An undercover police officer says the intention of a five-month operation involving alleged murderer Joseph ‘David’ Caissie was to discover the truth about what happened to his girlfriend Carol King, not to elicit a confession.
Caissie, now 55, could have denied any involvement in the killing, the officer noted on Thursday in Saskatoon Court of Queen’s Bench. His identity and those of all other undercover officers involved in the case are protected by a publication ban.
