Savanna Mohney, 14, and David Mohney, 11, were killed, deputies said. Their father, David Mohney, 52, was pronounced dead at the hospital, officials said.
The shooting happened at a home near Jackson Lane in the Spruce Creek Farms subdivision of Port Orange, which is about 5 miles south of Daytona Beach.
The Volusia County Sheriff's Office said the incident may have stemmed from an early morning domestic dispute between David Mohoney and his wife, Cynthia Mohney, 48.
Shortly after 5 a.m., Cynthia Mohney ran to a neighbor's house for help, saying her husband threatened her with a gun, authorities said.
