So it's a thriller movie that came out within the last 10 years.
I don't remember much but the ending is what I do remember.
So a guy accidentally kills someone (I think it's a woman, might be wrong). He tells his best friend or brother about it and they try to bury the body/evidence in the backyard. Eventually the sibling of the person they killed catches onto them and starts looking into them personally. At the end the sibling is close to digging up the body/evidence and either they moved the body/evidence or something distracts the sibling from actually digging. The 2 guys then drive away from the house, trying to get away either in an SUV or van, as they're looking back at the house to see if the sibling is following them they don't realize she's crossing the road in front of them and they hit and kill her.
Some of the details might be a little off but that's the gist of it. Anybody have a clue? It would be very much appreciated. TIA
