For the past several years, the "Heart Eyes Killer" has wreaked havoc on Valentine's Day by stalking and murdering romantic couples. This Valentine's Day, no couple is safe.
 
Leaves you sick at heart.
 
FUN FACT:  The two detectives investigating the Heart Eyes Killer murders are named "Hobbs and Shaw," a reference to "Fast and Furious" . The screenwriters confirmed that had always been the case, even before Jordana Brewster, who has played a large role in the series, was brought on as Detective Shaw.
