NASHVILLE — A federal judge has issued a stay of execution for Paul Dennis Reid, a death row inmate facing multiple death sentences for a series of slayings at fast food restaurants. Reid, a Texas drifter who came to Nashville to be a country singer, was convicted of killing seven people in Nashville and Clarksville in 1997. U.S. District Judge Todd Campbell ruled late last week that the Reid execution should be delayed. Reid’s execution had been set for Jan. 3.
