the pillar has collapsed:
CLEVELAND HEIGHTS, Ohio — Two young sisters in Ohio were fatally injured in a tragic hammock accident Sunday evening.
Local media reports the hammock was secured between a tree and a brick pillar, when, at some point while the girls were on the hammock, the pillar collapsed and landed on the sisters.
First responders arrived on scene and freed the girls who were rushed to a hospital—they died several hours later.
They were identified as 12-year-old Chasey Scaravilli and 14-year-old Scout Scaravilli.
