WEBSTER GROVES — Saturday’s fireworks show has been canceled after 11 people were hurt Thursday night when a shell misfired into a crowd during the city’s July Fourth show, officials said.

“Fire was all over the place,” said Brian Hardesty, of Richmond Heights. “My wife was stomping out balls of fire right near my 3-year-old’s face.”

The accident at Webster Groves Community Days prompted the city to cancel its second show planned for Saturday.

Officials said they would conduct a “full, complete and transparent review of everything that occurred on July 4.”

Thursday’s 20-minute show was about seven minutes from the ending when a mortar shell exploded, causing a nearby tube to shoot another shell “in a near horizontal manner” toward spectators, according to city officials. The shell exploded and sent fragments into the crowd. Injuries were minor, the city said, and treated on-site.

Hardesty said his family was sitting behind an orange fence about 75 yards from where the fireworks were being ignited. Thirteen minutes in, two fireworks popped but didn’t shoot up, he said. Then one shot right at them.

“It was a big one,” he said. “I’m surprised nobody got killed.”
