Two kids (both boys) are seen playing in a bedroom and with a gun that one of the kids found (I believe in that room).  The boy shoots him (who he was friends with) accidentally and it ends up killing him. I remember the boy that was shot falling into the closet and just laying there. After, police end up coming and I believe they start questioning the kid. Both the kids were young, I say early teens if not younger. I’m really not sure whether it was a movie or part of a tv show.
