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 items at a Rite-Aid drug store shortly after withdrawing less than $100 from an ATM and filling up her SUV with gas. The drug store is a short distance from the gas station.

Police also said Huston's husband, Kallen, passed a polygraph and continues to be cooperative with detectives.

Huston bought Gatorade, trail mix and a package of over-the-counter sleeping pills, according to police. Newberg Police Captain Jeff Kosmicki said the dose of pills Huston purchased was "non-lethal."

This new information adds another layer of mystery to the timeline of Huston's known whereabouts on July 24, the evening she disappeared.

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 less than $100 from ATM in Newberg, discovered by police through bank records her husband provided.

6:10 p.m. - Huston fills her SUV with about $40 of gas at the Circle K/76 station in Newberg, captured on surveillance video.

6:22 p.m. - Huston's mother sent her a text message, but never got a reply.

6:35 p.m. - Huston's iPhone stops sending signals.

Captain Kosmicki said Huston's family told police she frequently communicated with friends and family using text messages. He said it's unlike her to not respond to a message.

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 said 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 the Rite-Aid 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. Captain Kosmicki said the case is a "missing person" case since there is no evidence of criminal activity.

Another group of people met at a U-Haul store on NE Wilsonville Road, south of the area where Huston was last seen at the gas station and drug store along Highway 99, Tuesday evening to search for Huston. Most of the people in that group don't know Huston personally. They felt compelled to search for her because, as Shawn Barney said, "she's someone's daughter, someone's mother."

Captain Kosmicki said police are working with the Yamhill County Sheriff's Office to coordinate an official search for Huston. He expects that search to start early Wednesday morning. He said any civilian who wants to help search should call police or the sheriff's office for more information. This search for Huston will be coordinated, and police hope some of the people who've already been searching will volunteer to help police search.

Huston was driving a 1999 Lexus SUV with Oregon license WXH-011 when she was last seen five days ago. 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.
