A 56-year-old Iowa woman has died following an explosion at a gender reveal party, NBC News is reporting.

According to a press release from the Marion County Sherriff’s Office, police were called at around 4 in the afternoon on Saturday, with reports that a woman in Knoxville, Iowa had been injured.

The woman was pronounced dead at the scene when officers arrived. A subsequent investigation revealed that a piece of debris created by an explosion had struck the woman. No other information has been released at this time.

According to news station KCCI, the death is being investigated by multiple agencies, including the Bureau of Alcohol, Tobacco and Firearms.

Back in 2018, a US Border Patrol agent was found to have started a 47,000-acre wildfire that caused approximately $12 million in damage to property when attempting to undertake a gender reveal using a gun and Tannerite, an explosive compound often used as a shooting target.
