DES MOINES – Police said a gender reveal announcement that resulted in an explosion left one Iowa woman dead Saturday.

At about 4:03 p.m., police responded to a report that a woman, later identified as 56-year-old Pamela Kreimeyer, had been severely injured in an explosion, according to a news release from the Marion County Sheriff's Office.

When officials arrived at the scene in Knoxville, the woman was pronounced dead. Knoxville is about 40 miles southeast of Des Moines.

The woman was identified in a news release Monday from the Marion County Sheriff's Office.

The release said five family members and the expectant mother were present when an inadvertent "pipe bomb" created for a gender reveal exploded, "sending metal pieces flying." Kreimeyer, who was standing 45 feet from the device, was struck with one of the metal pieces and instantly died, according to the release.

Kreimeyer is remembered as a wife, mother and grandmother.

"This is a reminder that anytime someone mixes these things there is a high potential for serious injury or death; please do not take these unnecessary risks," Sheriff Jason Sandholdt said in a statement.

The incident remains under investigation.

This is not the first time a gender reveal party has ended in tragedy. In 2017, a gunshot at a gender reveal event sparked a wildfire in Arizona that caused $8 million worth of damage.
