Police suspect Timothy Britt was the triggerman in the murders of Miguel Avalos and his two sons.
Police say they've arrested a Omaha man on accusations that he fatally shot a southeast Omaha man and his two sons.
Timothy J. Britt was arrested Wednesday and charged with three counts of first-degree murder and three related firearms charges.
He's accused of shooting 44-year-old Miguel Avalos, 18-year-old Miguel Avalos Jr. and his 16-year-old brother, Jose Avalos, on July 9.
Police have said someone broke into the Avalos home and opened fire. Other family members in the home escaped injury.
Britt is the third person to be arrested in the case. Others are 33-year-old Anthony Davis, of Omaha, and 27-year-old Tiaotta Clairday, of Council Bluffs, Iowa.
