He was charged last year with threatening and assaulting his 25-year-old son at their Baxter home. Those charges were recently dismissed without prejudice, giving prosecutors the option of refiling charges.Richey spent more than 20 years on death row in Ohio for setting a fire that killed 2-year-old Cynthia Collins.
