Authorities say a central Florida man has been arrested after fatally shooting his teenage daughter and three other people. A Brevard County sheriff says 36-year-old Domenico Gigante was charged Wednesday with four counts of first-degree murder. Officials say deputies responded to a Canaveral Groves home early Wednesday morning after one of two surviving children had called a relative for help. The deputies reported finding the bodies of a 15-year-old girl and her mother. The girl's mother had previously been in a relationship with Gigante. The other two victims were identified as a 63-year-old woman and a 36-year-old man. Officials didn’t give a motive for the slayings. Gigante was arrested later Wednesday.
