RAYTOWN, Mo. — An explosion at a duplex in Raytown that killed one person and injured multiple others is believed to have been caused by someone making illegal fireworks, officials with ATF and the Missouri Fire Marshal announced Tuesday.

Police and fire crews responded to the duplex located near East 75th Street and Englewood before 7 p.m. At least three people were taken to the hospital with unknown injuries.

“He was trying to either make his own or create something bigger and this was the result and I just can’t emphasize that it takes very very very little pyrotechnic powder to cause a disaster like this,” said ATF spokesman John Ham.

Investigators discovered a body in the basement of the home Tuesday morning.

ATF said once the building is secure enough to go inside, they will retrieve the body and turn it over to the Jackson County Medical Examiner’s Office to be identified.

Anyone who has information that may help is urged to call the TIPS Hotline at 816-474-8477.
