A 15-year-old Redmond High School sophomore ran away from home Sept. 21 and her mother is now fearing the worst.

Jamie Stevens stormed out her parents’ home in unincorporated King County near the Woodinville-Redmond border three weeks ago and has not returned, according to Jamie’s mother, Judy.

“She left angry and frustrated and walked off with nothing but the clothes on her back, she has nothing, no money, no ID, nothing,” Judy said. “It’s really a big mystery.”

Judy and her husband, Jim, contacted all of Jamie’s friends and nobody had seen her the day she ran away. They went around the neighborhood, the high school and her favorite hangouts, hoping to find some clues that would lead to the whereabouts of their daughter.

Judy said she finally got an e-mail from her daughter the night of Sept. 29, telling her mother that she planned to come home soon and that she just needed some time to “cool off.”

But since then, “nobody has heard anything,” Judy said. “She has not been on Facebook or MySpace, she’s not responding to e-mails, so I know something is happening. She has stopped communicating with us and that’s our biggest concern.”

Judy and Jim are working with an investigator from the King County Sheriff’s Office, trying to find their runaway daughter, who got into a verbal altercation with her father before running away.

“We’ve done lots of follow-up work in this one but haven’t tracked her down yet,” said Sgt. John Urquhart, spokesperson for the Sheriff’s Office.

Judy said they have turned up some leads as to who she is with, and “it’s not good. They are people we don’t know and they seem to be caught up in bad things.”

Judy said Jamie “was frustrated and stressed out” with her home life, but Judy never expected her to run away and not come back. Jamie is a talented artist and was a strong student in the classroom, according to Judy. Jamie told her parents that she planned to compete for the Redmond High track and field team in the spring, Judy said.

“It’s very hard,” said Judy, who is also working with the National Center for Missing and Exploited Children. “She’s talented, she’s smart and she’s really engaging. I know wherever she is, it’s bad. I just don’t know how bad it is.”

Jamie has dark hair and is diminutive in stature, around 5-foot-2, 105 pounds, according to her mother.
