A Story for Halloween

During a brief conversation with my mom the other day, I found out the house my sister is renting has a story surrounding it. The reason it was available to rent is that the person living there recently died - in the house. The owner asked my sister if she had a problem with that and she asked, "Well, he wasn't murdered, was he?" The answer was no, so she didn't think much else about it. But now they're moved in and have met a few of the neighbors and she asked one of them how the guy died. Turns out he hanged himself in the basement! The basement is unfinished and on one wall is a big "I Love You" in spraypaint, which my sister thinks might have been his suicide note. So now she's totally creeped out whenever she has to do laundry. Doncha think the owner could have atleast painted over the "I Love You" before someone else moved in?
