A 34-year-old Hilo man has been ordered to stand trial July 15 on charges of first- and second-degree murder and firearms violations.
Sean Ivan Matsumoto pleaded not guilty Wednesday to killing 45-year-old Rhonda Lynn Alohalani Ahu, his girlfriend, and her mother, 74-year-old Elaine Ahu.
Police investigators say in court filings that Matsumoto on Feb. 11 called 911 and reported he had shot two people in his home.
The Hawaii Tribune-Herald reports he was still on his cellphone when officers arrived. They recovered a loaded 12-gauge shotgun.
Police say two children in the home were not harmed.
Matsumoto is being held without bail at Hawaii Community Correctional Center.
