A charge of murder was filed against a South-Central Los Angeles man whose 3-month-old son died of a fractured skull. Deputy Dist. Atty. Herman Jacobowitz filed the complaint charging Michael Hunter with the murder of Dante Hunter. The boy's mother, Ethel Mae Gray, 31, was charged with felony child endangerment. Police said the parents were arrested at their home on East 92nd Street on Dec. 12 after a coroner's autopsy found that the baby's Dec. 7 death was due to a massive skull fracture.
