KELSO, Wash. (KOIN) — A nocturnal heist left a marijuana growing facility in Kelso short $250,000 worth of product.

At least 5 thieves broke into Cascade Mountain Cannabis early Sunday morning.

Surveillance video shows the burglars cut a hole through the back of the building and head to a room where the plants are left to dry where they stuff 150 pounds of pot into bags over the course of 2 hours.

The owners of the facility told KOIN 6 News the stolen product had already been sold and was supposed to have reached retailers by now.

“It would have been our first fall crop trimmed up and packaged this week,” said Courtny Roberts, a co-owner of Cascade Mountain Cannabis.

Roberts said the business has operated at its current locations for nearly 3 years without incident. She said the security system’s motion detector cameras did not trigger an alarm.

But the cameras did manage to capture the faces of the thieves, some of whom took off their masks. Some of the cameras were destroyed by the group during the theft.

Some of them were wearing shirts with the word “Oregunian” on them. One of the thieves was a woman.

The owners are offering a $5,000 reward for information that leads to an arrest. Kelso police and the owners have already received some tips about the thieves’ identities.

“It’s a huge hit financially for our business. I hope we make it financially.”

Roberts said the grow facility won’t have another crop ready for several more weeks.

“Very surreal feeling — sick to my stomach,” Roberts said of the theft. “Couldn’t believe this happened, we work really hard. It’s our livelihood. To have someone come take it…”
