MEMPHIS, Tenn. (AP) — Authorities say a woman and her boyfriend have been charged with murder in the beating death of their 7-year-old son in Tennessee. The Shelby County district attorney's office says 42-year-old Michelle Williamson and 39-year-old Daryl Lee have been indicted on first-degree murder in the perpetration of aggravated child abuse and aggravated child neglect in the death of Tevaun Williamson. Investigators said the boy died at a hospital in November 2016 after he was beaten with a cable cord and his head was slammed to the floor.
