A Fourth of July event in California turned tragic when police reported that an illegal stockpile of fireworks “began misfiring” and hit a young girl, leading to her death.

According to the Buena Park Police Department, officers were conducting patrols in the 8000 block of Cornflower Circle in Buena Park, located in Orange County roughly 20 miles south of Los Angeles. At approximately 9:45 p.m. on Friday, they observed “a large quantity of fireworks detonate,” followed by family members “frantically” rushing a child into a residence.

The officers rushed to the child”s aid and said they saw a young girl, later revealed to be 8-year-old Jasmine Nguyen, suffering from “critical injuries, consistent with a fireworks-related explosion.” She was transported to a nearby hospital where she was pronounced dead.

An initial investigation revealed that “a large illegal fireworks display” was set up in the street by a homeowner on the block. The fireworks “failed and began misfiring toward the residence where the child was,” the police department said.

The erratic fireworks also reportedly caused others to ignite – near the child and other people. The child was struck at some point, “causing fatal injuries.”

No one else was believed to have been significantly hurt.

Earl Decastro, 46, was reportedly a neighbor of Nguyen – and the man hosting the party at which everyone was gathered. He was subsequently arrested on suspicion of involuntary manslaughter and was released on $25,000 bail, local news station KTLA reported, adding that any official charge would be filed by the Orange County District Attorney’s Office.

Lt. Jon Shaddow of the Buena Park Police Department called Nguyen’s death “traumatic.”

“I can only imagine what the family is going through,” he told the outlet. “I can only imagine what the officers are going through, especially the one who took control of the scene and had to do life-saving measures.”

An official cause of death has not been revealed, but Shaddow said it “looked like it was mainly just traumatic internal injuries.”
