One might call that a clue

Rico says lessee, the woman buys a gub, her football player boyfriend gets two to the head and two to the chest, and she gets one to the head, with the gub being found beneath her body. The cops say murder/suicide is "still on the table", but have determined no motive as of yet, and have questioned her ex-boyfriend but released him. (She was just 20, and Federal law prohibits anyone under 21 from purchasing a handgun, while Tennessee requires a person to be 21 to have a carry permit. A puzzler, fer sure...)
