NASHVILLE, Tenn. (AP) - Police are charging Timothy Smith with stabbing his 82-year-old grandmother to death.
Police say the 27-year-old checked himself into a mental health institute Tuesday morning.
That was shortly before they found the body of his paternal grandmother, Mary Margaret Smith, in the north Nashville home they shared.
Smith's mother called police after seeing blood on her son's clothes when she drove him to the Middle Tennessee Mental Health Institute for a substance abuse evaluation.
Smith is a registered sex offender who was previously convicted of child rape, assault, and drug possession. He is in jail without bond.
