Greg Parsons is pleading with the Premier for a review of how and why key evidence wasn’t used to sentence his mother’s killer.

Brian Doyle stabbed Catherine Carroll to death in 1991, but allowed Parsons to go to jail for it.

He did four years before he was cleared, while Doyle confessed in an undercover sting and was sentenced to 18 years before parole.

Parsons says the evidence omitted proves Doyle planned it all and should’ve been convicted of first, not second-degree, murder and given a longer sentence at a maximum security prison.

What’s more, the parole board has been using that evidence, supplied by Parsons, in assessing Doyle’s risk to reoffend.

Nonetheless, Doyle was granted day parole earlier this week from a minimum security facility in B.C. that’s been referred to as “club fed” and “condos for cons.”

Parsons insists his request for a review is justified, adding he’s disappointed Premier Andrew Furey hasn’t responded or acknowledged the wrongdoing.

“That’s the last thing I’m asking for, a simple judicial review by a judge out of province, obviously, to look at the evidence that was suppressed.”

Parsons and two others were the subject of a public inquiry into wrongful convictions. But that was before the additional evidence was given to him by former RNC Chief Robert Johnston shortly before he passed away.
