A Cambria County man was convicted Wednesday of first-degree murder for shooting another man outside a cabin in Blair County.

Shawn Dugan, 39, of Johnstown faces a mandatory life prison sentence for killing another Johnstown man, Marcus Chromy, 39.

Blair County District Attorney Richard Consiglio said Dugan, Chromy and a Johnstown woman went to the cabin on June 5, 2008. Prosecutors said Dugan got upset at the way Chromy was treating the woman and killed him two days later with a 12-gauge shotgun.
