Officials in Kittitas County have revealed the cause of a fire that destroyed a marijuana business near Thorp last week.

“They went outside to smoke a cigarette, and thought they had put it out correctly,” said Young regarding the actions which caused the fire at around 3 a.m. and led to the total loss of the structure that housed the legal cannabis operation.

The blaze was the second of three over a span of as many days in Kittitas County which could be traced to human causes.

Two days earlier, the Sun Country Fire was ignited by a malfunctioning vehicle trailer along Interstate-90 between Cle Elum and Easton, and on Aug. 21, the Pipe Creek Fire was sparked by a mobile home on the shoulder of U.S. Highway 97 near the summit of Blewett Pass.
