I remember from at least 10 years ago, probably longer watching a film.
3 homeless men rape a girl, one of them kills her but the other 2 don’t know, they are then visited by another girl who the killer likes, she leads them to an house where they find treasure, the killer leaves to get food to celebrate, he poisons it with rat poison. The other 2 wait and watch TV and see on the news about the girl being killed. When the killer gets back they beat him to death, then eat the food and die also.
It turns out the other girl who led them to the house was a ghost friend of the girl they raped and killed.
