A Calgary jury has reduced the parole eligibility period for a man convicted of killing an Okotoks teen in January of 1992.

Bradley Paetsch murdered Okotoks teen Stephane Spooner in a jealous rage. Paetsch, who has since changed his name to Tristan Ryan, was found guilty of first degree murder and sentenced to a minimum 25 years without parole.

He would not have been eligible for parole until 2016 but Tuesday's decision means he'll be eligible for full parole as early as 2014.

He has already been out on escorted day passes from the Drumheller penitentiary over two dozen times.

It's still up to the National Parole Board to determine if he is to be released.
