January 12, 1984. Atlantic City, New Jersey. Seven-year old Gary Grant Jr., the son of a local police detective, leaves his home after telling his mother he is meeting someone for an appointment. Two days later, Gary’s body is discovered in a vacant lot after he has been bludgeoned to death with a pipe. A 12-year old friend of Gary’s named Carl “Boo” Mason soon confesses to the murder and is charged with the crime, but since Boo has a mental disability and a low IQ, his confession is thrown out and the charges are dropped. Over the next three decades, Gary’s father would be taunted by cryptic graffiti and also uncover a recording of an anonymous 911 caller confessing to the crime. Was Boo Mason involved in the murder of Gary Grant Jr. or was someone else responsible? On this week’s episode of “The Trail Went Cold”, we examine the incredibly tragic unsolved murder of a police officer’s son. This episode of The Trail Went Cold is brought to you by Zola.
