The Knox County Sheriff's Office has concluded an inquest into the November explosion that decimated a Choto area home, without determining the ignition source. The incident, which ripped through a residence on Blue Water Way, was initially addressed on Nov. 20, 2024. According to the report released by the sheriff's office, a propane leak of unknown origin fueled the explosion, but the extensive damage from the consequent blaze prevented investigators from pinpointing the exact ignition point. "Due to the mass loss suffered from the resulting fire, the ignition source for the explosion was undetermined," the sheriff's officials stated, as reported by WVLT.

The property, estimated to be worth $4.5 million including its contents, was found in ruins with debris scattered as far as 150 feet from the blast site. No casualties were reported despite the magnitude of the event. The homeowner was not present at the time of the explosion and even firefighters and civilians emerged unscathed as emergency services managed to quell the flames using an estimated 10,000 gallons of water, as detailed by WATE.

The investigation, while extensive, ultimately yielded little in the way of definitive answers. "The fire is officially classified as “undetermined," revealed a Knox County Fire Investigation Unit report. Even with the expertise of fire investigator Jerry Glenn, the origin of the propane leak inside the mansion could not be ascertained. Glenn's finding in the "Origin and Cause Report" dictates that due to the level of destruction wrought by fire, an original point of ignition cannot be verified, as WBIR indicated.

Randy Maltsberger, a neighbor, recounted the fearsome power of the explosion in an interview with WATE, saying, "That was the loudest explosion I’ve ever been around. It shook the house. Knocked the pictures off our bedroom [wall], which it’s on the other side of." Even with such substantial accounts and the visible aftermath, the case remains closed pending any new evidence that might surface in the future. The sheriff’s office assured that if any new information comes to light, the case could be reopened and further scrutinized.
