Missing father, Travis Decker, who is suspected of killing his three young girls, was an 'active dad' and showed 'no red flags' before their deaths, his ex-wife's attorney has said.

A man in central Washington state is wanted on suspicion of murder after his three young daughters were reported missing and then found dead.

A search for Decker has been underway since the bodies of his three young daughters were found at a campground near Leavenworth on June 2.
