The castle flew onto the playing field at Regency Furniture Stadium, in Waldorf, as the Southern Maryland Blue Crabs baseball team was playing, according to a news release from Charles County officials.
A group of children were inside the bounce house when a gust of wind sent it flying “approximately 15 to 20 feet (around five to six meters) up in the air,” Charles County officials said.
The children who were inside fell before the bounce house, as it is known in the US landed on the field, according to the news release.
Onsite medical responders immediately tended to the children, with help from trainers from the baseball team and attendees of the game, authorities said.
The five-year-old boy was taken to a local children’s hospital where he was later pronounced dead, and another child sustained non-life-threatening injuries and was flown out to the hospital, the release says.
The Southern Maryland Blue Crabs postponed their Saturday night game due to the incident.
Charles County Government Commission President Reuben B. Collins II also expressed his condolences and thanked first responders.
“We extend our deepest empathy to the children and their families during this difficult time,” Collins said.
Waldorf is located about 45km south of Washington, DC.
