PHOENIX -- A Youngtown man accused of child abuse after his infant son suffered multiple broken ribs has been sentenced to three years in prison.
Maricopa County prosecutors say 19-year-old Benjamin Joseph Cooper also was sentenced Thursday to 18 years of supervised probation.
Cooper was arrested last October after he told authorities that he squeezed his crying child while trying to swaddle him in a blanket, then heard a popping sound.
Authorities say Cooper also told them that he accidentally dropped the 5-week-old boy in a bassinet and the infant hit his head on the crib.
A social worker at Banner Thunderbird Medical Center notified authorities after the infant was treated for dehydration and a bruise on his cheek. Medical staffers say they saw the broken ribs on X-rays.
