Kouren-Rodney Bernard Thomas, a young black man shot to death while leaving a house party — allegedly by the host’s white neighbor — was described by his mother Tuesday as loving, funny, and so careful that his family called him “Safety 101.”

Kouren-Rodney Bernard Thomas was killed early Sunday when a man living two doors down from the party called police to complain of “hoodlums” in his neighborhood, and then fired a shotgun out of his garage, according to authorities and 911 tapes.

The suspect, Chad Cameron Copley, has been charged with murder.
