HELENA, Mont. -

A Lewis and Clark County jury has convicted a 49-year-old Maryland woman of sneaking into her estranged husband's Helena residence and killing him and his lover in October 2011.
Michelle Coller Gable was convicted Wednesday of two counts of deliberate homicide in the shooting deaths of 48-year-old Joseph Gable and 50-year-old Sunday Cooley Bennett.
Prosecutors argued Michelle Gable was jealous of Bennett and feared losing her husband's financial support in a divorce so she sneaked into his house with two guns on Oct. 13, 2011 and surprised the victims in bed just before dawn.
Defense attorneys argued Joe Gable attacked Michelle Gable when she awakened him and pistol whipped her. Michele Gable said the gun went off during a struggle, hitting Joe. She testified she shot Bennett because she was coming at her.
