The father of a missing 38-year-old Dundee woman said Sunday night that the search for his daughter would continue Monday with the hope that she will be found.

But Bill Turner said he and his wife, Deborah Turner, are "scared to death. We're absolutely scared to death," with the mystery surrounding the apparent disappearance of their daughter, Jennifer Huston.

Turner said there were no significant developments Sunday in the search for their daughter. He said a friend of his daughter and her husband, Kallen Huston, personally conducted an air search of the Yamhill County area near Newberg and Dundee with the hope that some trace of Jennifer Huston might be seen. The search was not fruitful, however, he said.

In addition, there was no usage of Huston's credit cards nor activity on her mobile telephone.

Huston went missing Thursday after purchasing gas at a 76 gas station in Newberg.

Surveillance video shows Huston purchasing gas at 6:10 p.m. Thursday. Huston appeared to be alone in her vehicle, a dark green Lexus LX-470. The license plate is WXH-011. Turner said the station is about a nine-minute drive from the family home.

Huston, a mother of two, was last seen wearing black and pink Nike shoes and yoga pants, according to a flier her family posted on social media and shared with media outlets. She is 5-foot-7-inches tall and has blond shoulder-length hair and blue eyes.

A Facebook page the family created to share photographs and information, "Find Jennifer Huston," had more than 10,000 likes Sunday night. Turner said the page administrator, a family friend, said the "Find Jennifer Huston" page had been viewed more than 400,000 times.

"We've been thankful for the support from neighbors in the community," Turner said. "We're really blessed to have people in the community of Newberg and Dundee who want to help."

He added that the family was grateful for media attention, noting that "Good Morning America" is expected to mention the case.

Turner and his wife have made the one-hour, one-way trip to the Dundee-Newberg area from their home in the Salmon Creek neighborhood north of Vancouver in Clark County.

Turner said her daughter and son-in-laws two sons, ages 3 and 6, have been told their mother is on vacation.

"She's a bright, vibrant person. She's a loving mom," Turner said. "She looked like she could be a model. She's the person who everyone will gravitate to and will want to talk to."

Records of Huston's phone activity earlier in the day Thursday showed "nothing out of the ordinary," Turner said of his daughter, a stay-at-home mom. "No unusual phone numbers or texts (and) fairly light for phone calls."

Huston and her husband met through mutual friends when both lived in Washington state, Turner said.

Turner said he and his wife are aware that attention is often focused on the remaining spouse when one has gone missing. That attention would be misplaced, he said.

"Our son-in-law is absolutely solids," Turner said. There is no concern that there is any foul play on the father's part. We trust him completely."

He said the young couple have a loving relationship.

"The best way to describe the relationship, the way my wife describes it, is two old souls living together," he said.
