 In "The Twisted Bones in the Melted Truck", Booth mentions an eccentric aunt of his, who "spent every last dime on old-fashioned cookie jars".On multiple occasions in the series, characters have stated that Booth is a direct descendant of infamous assassin John Wilkes Booth.However, this is historically inaccurate, as the assassin died childless at the age of 26 just days after killing Abraham Lincoln.
