FORT WAYNE, Ind. (AP) — Authorities have identified three people who died in a weekend fire in northeastern Indiana as a mother, father and their 12-year-old son.

The Allen County coroner's office on Tuesday said 43-year-old Amber Dawn Shaw, 46-year-old Larry Bernard Shaw and their son Elijah Shaw all died as a result of injuries in the house fire early Saturday in the Fort Wayne area. A fourth person in the house was injured.

The coroner's office says Larry Shaw and Elijah Shaw died at the scene while Amber Shaw was pronounced dead at a hospital.

The cause of the fire is under investigation. Fire crews from several departments responded to the fire and worked for about two hours to get it under control.
