Eighteen years after a 75-year-old woman was found slain in her home, her son was sentenced to prison for killing her. Richard Givens fled after killing his mother, Naomi Miller, in 1986 in the Cincinnati suburb of Norwood. Years later, he called Norwood police from out of town to confess that he killed his mother during a fit of rage. Police had to wait until this year - when Givens finished serving a prison term for a criminal conviction in Canada - before he could be brought back to Ohio to face charges. Yesterday, the 62-year-old Givens was sentenced in Hamilton County Common Pleas Court to 25 years in prison on a conviction for voluntary manslaughter. He could be eligible for parole after seven years.
