The man accused of killing his wife and hiding her body in their family home for two years was the target of an undercover police operation.

A year-longMr. Big stingwas carried out, resulting in the charges, according to Shyback's lawyerBalfour Der.

Such operations involve undercover officers pretending to be criminals who befriend the target with the ultimate goal of eliciting a confession to the crime the target is suspected of committing, most often a homicide.

After court, Der said he'll have to review disclosure before deciding if he'll challenge the admissibility of the evidence gathered as part of the undercover operation.

Mitchell, 31, was last seen at her home in the southeast community of Ogden on Oct. 29, 2012. Her family reported her missing to Turner Valley RCMP onNov. 12of that year.

In December,police executed a search warrant at Mitchell's Ogden home and say they found what are believed to behuman remains.

Shyback and the couple's two children had been living there since her disappearance. Police have said it will become clear through the court process why nobody noticed the presence of human remains for two years.

Shyback will be back in court onFeb. 26.
