One of the suspects brandished a gun in each hand as she threatened to kill office workers.
The owner of that dispensary is now offering his own reward, $2,500 for a name. He said the video is so clear that someone out there has to recognize them.
The suspects walked in with their guns drawn and ordered two workers to the ground.
"I'm going to cut your fingers off, I'm going to kill you guys, let's kill these two," recalls the owner.
The dispensary owner is angry after watching the surveillance video, two women and a man were armed and held his brother and another worker at gunpoint. The three suspects had no idea that the cameras were capturing their every move. The workers were tied up with zip ties as guns were pointed at the back of their heads.
"To me that's cowardly, these individuals are cowardly to force guns on people," said the owner.
The suspects opened a safe and threw money into a suitcase. The owner believes these suspects have struck before, robbing other businesses near 14th Street and Thomas.
"I think this area is a target, I think there is a group in the area, and that law enforcement needs to get together and get them all rounded up," he said.
The suitcase was filled with so much money it was heavy and difficult to carry. Once outside, the three suspects drove off in a Gray Chevrolet Pickup, the bed of the truck was painted red.
"All we need is one name, one positive ID of any of these three individuals. That's all we're asking for, a positive ID, and $2,500," said the owner.
