A missing Oregon mother bought Gatorade, trail mix, and over-the-counter sleeping pills before she disappeared, police said Tuesday. 

Police released new details about Jennifer Huston's actions on the evening of July 24, saying that they hoped it would lead to additional clues in the case. 

A previous timeline released by investigators said that Huston had left her home in Dundee, approximately 25 miles southwest of Portland, at 5:45 p.m. She stopped at a credit union in the nearby town of Newberg, where she withdrew fewer than $100 from an ATM. Huston then went to a nearby gas station, where investigators believe she topped off the tank of her SUV. 

On Tuesday, authorities added a new detail to the timeline: that Huston stopped at a Rite Aid after getting gas and bought the sports drink, trail mix, and store-brand sleeping pills. Investigators said that the amount of sleeping pills Huston had bought would not have been enough to induce a fatal overdose. 

Investigators believe that Huston's SUV could travel between 300 and 350 miles on a full tank of gas. 

A police statement released Tuesday said that Huston's husband, Kallen, had "been cooperative through several interviews with police and has passed a polygraph examination."

Authorities also said that there had been no confirmed sightings of Huston since she disappeared.

Jennifer Huston stands 5 feet, 7 inches and has blonde hair and blue eyes. She was last seen wearing black and pink Nike shoes and black yoga pants. She drives a dark green 1999 Lexus LX 470 with Oregon plates WXH 011.

The SUV had a U-shaped crack in the windshield on the passenger side and a Yakima ski rack mounted on the roof.
