Police: Before vanishing, missing mom bought trail mix, sleeping pills

NEWBERG, Ore. - Police released new details about the search for missing Dundee mom Jennifer Huston on Tuesday night, adding another layer of mystery to her disappearance.

Detectives discovered Huston bought supplies at a Rite-Aid drug store shortly after withdrawing money from an ATM and filling up her SUV with gas. Police also said Huston's husband, Kallen, passed a polygraph and continues to be cooperative with detectives.

Huston bought Gatoraide, trail mix and a package of over-the-counter sleeping pills, according to police.

This new information adds another layer of mystery to the timeline of Huston's known whereabouts on Thursday evening.

5:45 p.m. - Jennifer Huston leaves her husband and two boys at home in Dundee to run errands

5:59 p.m. - Huston withdraws "small amount of money" from ATM in Newberg, discovered by police through bank records

6:10 p.m. - Huston fills her SUV with gas at Circle K in Newberg, captured on surveillance video

6:25 p.m. - Huston's iPhone stops sending signals

Meanwhile, Huston's family insisted she would never intentionally vanish from contact and continued their own searches.

A close friend of Huston's said she was preparing to celebrate her 10-year wedding anniversary with her husband, Kallen, which was coming up in the next week or two.

Huston's father, Bill Turner, said family and friends organized a search on Monday evening of the Willamette River.

Turner says they focused on areas Huston often spent time, including the banks along Champoeng State Park in Newberg.

Newberg detectives continued scouring the area for clues by asking businesses along Highway 99 all the way to Portland for their own surveillance footage, hoping to spot Huston's green SUV.

As of Tuesday afternoon, a spokesman for Newberg Police said detectives had not been able to identify Huston's SUV because the road was crowded with traffic.

Police also said they do not know if Huston stopped for gas anywhere else on Thursday and were estimating she could travel 300-350 miles on the full tank from Circle K in Newberg.

There is no evidence of foul play, according to the official police statement Tuesday night, and Huston's family continues to be helpful and cooperative.

Huston was driving a 1999 Lexus SUV with Oregon license WXH-011. Police say there is a "U" shaped crack in the windshield on the passenger side and there is a Yakima Ski Rack mounted on the roof.
