Nebraska State Fire Marshals are still investigating who caused the Wardrobe Spa to explode Sunday after tampering of the gas delivery system, according to investigators.
Bits of brick and glass still litter the property. Papillion fire chief Bill Bowes says the evidence that helps investigators is often destroyed by the blaze.
"Because there's so much damage, it's often hard to figure out who was there to start the fire," Bowes said. "So the canvas is really blank, so you have to start looking at who had access and who had a reason."
This investigation is still ongoing, evidence is still being collected, and officials no longer have custody of the site, according to State Fire Marshals.
Sarpy County Attorney Lee Polikov says in cases like this, investigators look for any kinds of statements, residual evidence, or any sorts of patterns.
