But it’s still shocking what caused it: a cigarette smoked by the local police chief.

On the morning of Aug. 7, firefighters arrived at the Vienna Point Residential Care Center to find the building engulfed in flames.

The blaze could be seen venting through the roof.

According to the Missouri State Fire Marshal’s report, strong winds and limited water supply kept crews from stopping the fire from spreading.

No injuries were reported, but the building was a total loss.

Initial findings listed the cause as undetermined due to the extensive damage.

However, the investigation was revised on Nov. 5 after insurers provided security video from the night of the fire.

That video footage shows Vienna Police Chief Shannon Thompson arriving at the facility just before midnight on Aug. 6 in response to an accidental 911 call.

After smoking a cigarette and placing it in a planter near the front entrance, Thompson returns several minutes later and appears to stop at the planter before leaving.

About 90 minutes later, video shows a small glow develop in the planter, which transitions into open flames that spread to the building’s entrance.

Thompson later told investigators that he tried to put the cigarette out before leaving and said he didn’t think it could start a fire. He also noted the cigarette he smoked is designed to self-extinguish.

Investigators concluded the fire was accidental. It started when the cigarette was placed near combustible material and smoldering embers weren’t noticed.

Even though the fire was an accident, Thompson could still face charges. Prosecutors have not decided whether they will file charges.
