Someone nearby where I live was killed when something like that happened once a few years ago. A guy was shooting at a rabbit that was sitting on the crest of a hill. One of his bullets went over the crest of the hill, through a glass greenhouse and killed someone in the greenhouse.
The Utah Highway Dept mistakenly lobbed at least one avalanche shell over a ridge that landed in someone’s backyard in Provo(?). Good thing it only moved some mud around.
