Yesterday I got a call from the Martinez Police Department. He was returning my call, and while confirming what had been stolen and getting the Contra Costa County Sheriff's case number, he asked if I knew Jennifer.
I said that yes, she's my wife.
He said that they had found her high school class ring. It of course had the year she graduated, but also had her initials on it. He had then gone to Ygnacio and looked at the yearbook for our senior year, and he said there were only two people with those initials in our graduating class.
I am so excited. I know it's no guarantee of anything, but it is at least one item that has been recovered. Plus it will be a piece of evidence towards conviction of the fence and maybe a lead toward apprehending the thieves.
