• Guilty plea in Newfoundland murder case that sent innocent man to jail

On New Year's Eve 1990, Doylewent to Catherine Carroll's St. John's home, broke in through a basement window and stabbed and slashed her 53 times.

Carroll's son Greg Parsons was tried for murder and found guilty. But in 1998 DNA evidence cleared his name.

Doyle, now 48, was sentenced in February 2003 to life in prison with no chance of parole for 18 years.

He was arrested after a lengthy police investigation in Ontario.

Police got Doyle to join a fictitious organized crime outfit. He agreed to run contraband tobacco and alcohol. And when one of the undercover officers told Doyle that he wanted his wife dead, Doyle offered to do it for him.

The undercover officers told Doyle that first they needed to know everything about him, including how Catherine Carroll died. That's when Doyle told them everything.

Inquiry exposed tunnel vision

The provincial government apologized to Parsons in 1998 and later compensated him, four years after he was convicted.

In 2006, an inquiry led by Justice Antonio Lamer concluded that poor police work and tunnel vision led to the wrongful conviction.

"The investigation and prosecution of Gregory Parsons became a 'runaway train,' fuelled by tunnel vision and picking up many passengers along the way," Lamer wrote at the time.

Parsons is not yet ready to comment on Doyle's request to the parole board.
