Mark Gooch, 21, was arrested Tuesday at Luke Air Force Base near Phoenix, where he was stationed.
The three were arrested earlier this month in Flagstaff after Ann Marie Martinez called 911 and said she thought her grandson was dead. An officer noted he could have been dead for hours. Eventually, they told police they kept the boy and his 7-year-old brother in a closet for 16 hours a day over the past month and gave them little to eat, police reports showed. Police said the boys’ confinement in a closet was punishment for stealing food while the parents slept.
