KATU News has learned the San Juan County Sheriff's Office is following up on a tip about a possible Jennifer Huston sighting on Thursday in Washington.
A couple thought they saw Huston's green SUV on a ferry going to Friday Harbor from Anacortes, according to the sheriff's office.
The couple could not confirm the license plate number.
The sheriff's office has requested surveillance video from Washington state ferries.
Meanwhile, Jennifer Huston's husband and father joined KATU News for an interview on Sunday morning to talk about the latest developments in the search.
"It's been an emotional time for the family. Lots of ups and downs," said Kallen Huston, Jennifer's husband. "These leads get us excited for a short bit, then reality sets back in and it's been difficult."
Kallen Huston said the family doesn't know yet if the new lead is credible.
"The islands are small and it should not take a long time to search," he said. "We've vacationed many times there in the past."
Huston's father, Bill Turner, says he believes Jennifer is still in Oregon.
"I believe she's within 25 miles of Newberg," Turner said.
"We are still searching the parks and places she could have gone within walking distance," he said.
