HELENA – Police say a Montana man shot and killed his estranged wife before killing himself during a girl's birthday party.

Helena Deputy Chief Steve Hagen says the man was at the party Tuesday night for a time and then ordered some of the people out of the house. He pulled a gun and the remaining party guests fled.

Police say he followed the woman outside and shot her in the front yard before turning the gun on himself.

Responding officers found both victims, who were 37, dead outside the house.

Police did not find any additional victims. Details about the birthday party were not immediately released by police.
