One child was killed and another was injured after a wind gust blew a bounce house into the air at a baseball game in Maryland on Friday night, local officials said.

Local emergency personnel received a call in Waldorf, Maryland, at about 9:21 p.m. Friday from the Regency Furniture Stadium reporting that a moon bounce house became airborne because of a wind gust while children were inside.

At the time, the Southern Maryland Blue Crabs minor league baseball team was playing a game, and “the moon bounce was carried approximately 15 to 20 feet up in the air, causing children to fall before it landed on the playing field,” according to a news release from the Charles County government posted on its website.

A 5-year-old boy from La Plata, Maryland, was flown to Children’s National Hospital in Washington, where he was later pronounced dead, the release said. A second child also was flown out by Maryland State Police with non-life-threatening injuries.
