The family of a missing Hanford High School honor roll student said the girl bought a plane ticket and ran away from home.
Sasha Townsend's family traced a debit card she apparently used to buy a ticket from Pasco to Indianapolis on Friday night, said her father, Phil Townsend.
"Unless it was someone else using her ticket and passing as her, we are presuming it was her that used the (debit card) for the trip," Townsend said.
Sasha, 17, has been missing since shortly after 5 p.m. Friday when she reportedly left the high school. Her family has contacted the National Center for Missing & Exploited Children for help.
Never miss a local story.
Richland police are also working to try and track down Sasha's whereabouts. Her information has been entered into a national database used by law enforcement agencies to locate property and people.
Sasha was taking AP classes at Hanford and is a talented artist who has a good heart, Townsend told the Herald.
She left a letter saying goodbye to her family and notifying them she was running away, Townsend said. She has battled depression in the past.
Townsend said his daughter ran away last summer, though the letter she left this time has him worried for her safety.
"We welcome any thoughts and prayers," he said. "We are hoping for Sasha's safe return."
