Investigators say hundreds of pounds of explosives used for making fireworks were present at the site of last week's deadly home explosion in Buena.

The blast killed four people, including two identified as minors whose names have not been released.

Authorities say the large quantity of fireworks materials is what caused the explosion.

The bodies of two other victims have yet to be identified as county medical examiners continue working on the case.

The powerful explosion destroyed the home on the 300 block of East Wheat Road last Friday morning. Debris was scattered over a wide area, and neighboring houses were damaged.

Authorities have not provided details on why the explosives were on the residential property.
