The death of a Hoover man was ruled a homicide, authorities said Tuesday. An autopsy concluded that Arthur Grey Till Jr. 73, died as a result of blunt force trauma, police said. The body was found Monday afternoon by friends visiting Till's home on Crossings Drive, off Caldwell Mill Road, investigators said. Detectives said there were no signs of forced entry. There have been no arrests in the case. Evidence at the scene suggests "foul play may be involved," police said.
