SANTA CRUZ, Calif. -- A surveillance camera captured two suspects throwing a Molotov cocktail into the window of a medical marijuana dispensary early Saturday morning.

Two more cameras inside the business recorded images of the lobby of the local marijuana dispensary going up in flames at around 2 a.m.

Moments before the attack, the tape showed two people wearing hooded sweatshirts and bandannas over their faces approaching the building.

Then, one of the suspects began hammering a glass door, while the other lit a large Molotov cocktail and threw it inside.

Owner Chris Morganelli and his partner were the first at the scene after getting a call from their alarm company.

“I couldn't really believe what I was seeing on the video,” said the dispensary owner Chris Morganelli

Morganelli said he used a garden hose to keep the fire from spreading to a second room where he kept much of the marijuana.

“Everybody seems like they're coming at us and saying, who do you think did this? Um, I don’t really speculate,” Morganelli said.

The owners said they are hoping their sophisticated surveillance system will help track down the people responsible.

“We just finished a remodel on this place, so we've dumped tons of money and to see it go up in flames is just devastating,” said co-owner Brianna Kovach.

The owners of this place said they have about 1,000 patients and some volunteered to help clean up after the explosion.

A local group, CannabisHealers.org has already put up a $5,000 reward for information leading to an arrest.

Police said the fire caused an estimated $50,000 in damages.
