On Tuesday, investigators said an autopsy confirmed the death of Annie Bailly.
Investigators are at her home in Penngrove, the last place she was seen.
Her husband reported her missing in December 2014. Though she disappeared, her car, keys, and purse remained behind.
Her body was found at Point Reyes National Seashore last month.
People involved in a crash spotted her remains down an embankment.
Investigators said evidence shows she was murdered, though they have not said how.
