An Oshkosh man is charged with first-degree reckless homicide in the apparent shaking death of his seven-week-old son. The baby’s mother left the boy in Cory Lyons’ care November 29th. Police who followed up on the child’s death say Lyons changed his story more than once, then admitted he shook the boy, saying he was frustrated he wouldn’t stop crying after soiling his diaper. Death was caused by a brain injury.
