Two Washington residents are accused of trafficking close to nine pounds of heroin and cocaine after they were pulled over on Interstate 5 near the California border.

Adam Tyler Smith, 44, and Bonita Alvarado, 44, both of Seattle, each face felony drug possession and delivery charges after police seized 6.6 pounds of heroin and 2.2 pounds of cocaine Monday from the 2017 Nissan Maxima sedan they were driving just after noon on northbound I-5.

Smith had no form of identification on him in the car, according to police, and an Oregon State Police trooper allegedly spotted a kilo of cocaine between Alvarado's feet while scanning for a wallet.

During a search, police said, they found three additional packages of drugs in the car that contained 6.6 lbs of heroin. Inside Alvarado's purse, police found $1,680 in cash and a small amount of methamphetamine, court documents say.

The pair had allegedly been traveling from Los Angeles to Seattle, according to police. Court documents claim Smith admitted to police that he was paid to assist with transporting drugs.

Smith and Alvarado were booked Monday in the Jackson County Jail and released Wednesday, records show. Smith's next court appearance is set for Dec. 5, and Alvarado's is set for Dec. 29, court filings show.

The arrest was aided by the federal High Intensity Drug Trafficking Area program, according to the release. The program, funded by the United States Office of National Drug Control Policy, funds additional troopers, K-9 units and drug enforcement detectives.
