A Tennessee grandpa has been arrested for allegedly killing his grandson, after he didn’t have dinner ready on time. 63-year-old Harold Gray has been charged with second-degree murder in the death of 31-year-old Anthony Morris. Police say Gray returned home from work on April 25th in Memphis. The two argued and Gray told police Morris hit him in the face twice. That’s when police say Morris followed Gray outside and stabbed him with a knife. Gray is currently being held – at the Shelby County Jail.
