FLORENCE - An Arizona death-row inmate who murdered his wife and young daughter has died in what the Department of Corrections is calling an apparent suicide.

The department said the death Friday of Milo Stanley, 50, will be investigated by the department and medical examiners. Details on how Stanley died weren't immediately available.

Stanley was convicted in Yavapai County of murdering his wife, Susan, and 5-year-old daughter, Seleste, in 1986 during an argument with his wife over his drinking.

Stanley dumped the bodies in a remote area, returned to his Clarkdale home, put his 1-year-old son to bed and then called police to report his wife and daughter missing.

He was sentenced to death for the daughter's death and to life in prison for killing his wife.
