This week, we take a look at a love triangle that almost certainly went horribly wrong.

Heather Elvis was 20 years old, studying cosmetology by day and waiting tables in Myrtle Beach at night. In the summer of 2013, she began a whirlwind fling with a married man.

That December, she disappeared. Never to be seen again.

This week, we take a look at the circumstances behind her disappearance and likely untimely death.

BUT FIRST! This Week in Murder takes a look at a fatal mask dispute at a restaurant that totally doesn’t sponsor this show and a case of incredibly awful parenting.

And, as always, we end with Who Died The Worst!
