Authorities in eastern Maryland say a man, woman and a 2-year-old girl are dead following an apparent murder-suicide.

Calvert County officials say 32-year-old Frank Hayward killed his wife, Cynthia, and the couple's daughter before killing himself Tuesday morning inside the family home in Owings.

Sheriff's deputies found the bodies after responding to a report of a domestic disturbance.

The couple's 12-year-old son was being treated at a hospital for burns and lacerations to the neck. There was a fire in the home when authorities arrived, and officials say Hayward had barricaded himself inside the home and was making threats.

No motive was immediately revealed.
