(KTXL) — A video of a man buying drugs, suspected to be fentanyl or laced with fentanyl, and collapsing from an overdose shortly after was shared by the Placer County Sheriff’s Office.

The incident took place at a gas station on Dec. 3, the sheriff’s office said.

In the video, you can see a person walk up to a dark-colored pickup truck parked at one of the pumps at the gas station and conduct a transaction with the driver of the truck, the sheriff’s office said.

The buyer can then be seen trying to walk into the gas station’s store before collapsing in the doorway.

When deputies responded, following a call for medical aid, they assisted medical personnel and were able to revive the man.

Deputies identified Colten Watkins, 29, of Roseville, as the alleged seller, and on Dec. 5, detectives served a search warrant at Watkins’ home.

Law enforcement discovered a non-serialized AR-15, two 30-round magazines, a digital scale, a notebook with a pay-owe sheet and additional ammunition.

During an additional search of his vehicle, law enforcement discovered 8 grams of suspected fentanyl, 3.8 grams of suspected methamphetamine, several pills, a black digital scale and several other items.

Watkins was arrested and is facing charges of “narcotics for sale, transportation of a controlled substance and being a felon in possession of a firearm.”
