It was supposed to be a day of celebration.
On Saturday afternoon, six members of an Iowa family gathered outside a rural Knoxville, Iowa, home for what society has dubbed a "gender reveal" party. Among the six was a pregnant woman. Her family was there to learn the sex of her baby.
But the reveal - which involved a homemade explosive device - went horribly wrong, shooting metal shrapnel toward the family standing 45 feet away.
Pamela Kreimeyer, 56, was struck in the head. She died on impact, officials said.
