A duffel bag filled with marijuana and hallucinogenic mushrooms was found on a night bus in Olympia, Washington, on Sunday.

Surveillance video appears to show 43-year-old Michael Henderson getting on the Intercity Transit bus on Sunday, sitting down and putting his large duffel bag beside him.

At one point, he gets up to allow a wheelchair rider to have a seat. He appears to remember the bag at first, but when he gets off the bus, he leaves the bag behind.

"I come back and there's a bag on my bus," said bus driver Bill Smith. Smith said the bag had a familiar odor. "I smelled something that smelled of marijuana."

Surveillance video then sppears to show Henderson coming back the next day to get his bag. By then, Olympia police knew what was in it.

"Four different tubs of marijuana and what we believe are hallucinogenic mushrooms," said Laura Wohl, Olympia police spokeswoman.

There also was a wad of more than $440 – most of it in $20 bills – a scale and small zip bags.

"It was obviously done with intent to sell," Wohl said.

Smith said it still baffles him.

“Like I said, I couldn't tell if the bag itself smelled like marijuana or if there’s something in it," Smith said. "But I didn't want to find out."

“It was time for a change in my life,” Henderson said to an arresting officer.

Henderson was arrested on suspicion of possession of narcotics with the intent to sell. He has been booked into Thurston County Jail while prosecutors try to decide what charges to file against him.
