Dominguez got married Friday. He and his bride had a party Saturday night at their home. Relatives say an argument broke out early Sunday with some guests and the groom's brother ended up being stabbed.
Police say Dominguez and his wounded sibling chased two alleged attackers to another home. Police spokesman Kese Smith says Dominguez and his brother tried to enter the residence by kicking and beating on the door.
Police say a person inside opened fire. Dominguez died at the scene.
Police say his brother is expected to recover.
