Officials said the husband was the first to be attacked while the wife guided their two children to safety before returning in an attempt to help her husband.

Andrew James McGann, 28, was arrested at 4:57 p.m. local time on July 30 at a business in Springdale, Arkansas, state police said.

Arkansas police say the killer of a married couple who had been hiking the remote Devil’s Den State Park with their young daughters was likely injured during the weekend attack.
