Marin County Sheriff's Office says they received four "independent alerts from Cadaver K9 teams" near Shell Beach along Tomales Bay.

In a statement issued by the Marin County Sheriff's Office, they write: "We've worked tirelessly combing through all leads and areas surrounding the cottage they were vacationing at and are now calling this a recovery mission. We have been in close contact with family and will continue to search for Carol and Ian. Our thoughts are with the Kiparsky and Irwin family during this difficult time.


Carol Kiparsky, 77, and Ian Irwin, 72, were on a hiking getaway and staying at an Airbnb cottage in Inverness. Family members they last heard from the couple on Friday, but the Airbnb owner called police when the couple didn't check out as scheduled on Saturday.
