A California man’s alleged drug haul was foiled after he accidentally left behind a backpack containing a massive stash of suspected methamphetamine in a rideshare vehicle, officials said.

The San Francisco Police Department (SFPD) said authorities recovered roughly three-quarters of a pound of suspected meth after the rideshare driver contacted officers Sunday afternoon.

The drugs have an estimated street value of more than $30,000, according to treatment directory Recovered, which cites typical prices of up to $100 per gram.

Police identified the suspect as 41-year-old Sacramento resident Jessie Ottman-Combs.

Authorities said they quickly located Ottman-Combs after working with the rideshare driver to arrange for the backpack to be returned to its owner, ultimately leading officers to a motel where he was staying.

During a search of the motel room, officers reportedly recovered two cellphones, two tablets and drug paraphernalia.

Police seized all the items, along with the suspected methamphetamine found in the rideshare vehicle, as evidence.

Authorities recovered 355.7 grams of suspected methamphetamine.

Ottman-Combs was booked into the San Francisco County Jail on charges of possession of methamphetamine, possession of drug paraphernalia and transportation or sale of methamphetamine.
