WILSON CREEK - Family members are seeking information on the whereabouts of a 15-year-old girl who disappeared Sept. 2.

Tori Diamond is about five feet, seven inches tall, has brown hair and blue eyes and weighs approximately 140 pounds, said her mother Brandie Diamond, on Tuesday. She might be wearing black glasses, she said. The Grant County Sheriff's Office is investigating the disappearance as a missing person, said Kyle Foreman, a public information officer for the sheriff's office.

Tori has not contacted anyone since she left her house 10 days ago, "not her friends, not her dad, not me - nobody," Brandie Diamond said.

Tori left the family home in Wilson Creek, accompanied by her younger sister, after a dispute, Brandie Diamond said. Her mom sent her texts asking her return, and her younger sister did come home but Tori did not, she said.

"This is totally out of the normal for her," Brandie Diamond said.

Tori might have gone to Cle Elum or Sandy, Ore., where she has family, Diamond said. There was a report she might have been seen Sept. 8 in Moses Lake, her mom said.

Brandie Diamond said if Tori is listening, she should call her mother or another family member.

Foreman said the case is under investigation. Anyone who has information on Tori's whereabouts or her case in general can contact the sheriff's office at 509-754-2011, ext. 468. Anyone who wishes to leave anonymous information can e-mail it to crimetips@co.grant.wa.us.
