We have been receiving great response to Steve Lopez's article in the LA Times.
Many people have emailed volunteering to help - including several detectives/investigators, both active and retired. They have provided us with several ideas on other organizations to contact that might help disseminate Nancy's information more widely.
Of particular note is a former fraud investigator who states that the theory that Nancy is being kept in a care facility, possibly for fraudulent purposes, is right on the money. He related several anecdotes of abusive practices and shady operations. There is a set of investigative articles on this in the Sacramento Bee: http://www.sacbee.com/news/investigations/article2573412.html
From this situation, and with the help of Molly Davies - the Vice President for Elder Abuse Prevention and Ombudsman Services at WISE and Healthy Aging, we were able to get a large holding firm of care facilities to send Nancy's flyer to all of their administrators - possibly much more efficient then our group calling/visiting that many facilities.
There were also several "tips" of people that might be Nancy, but so far, of course, none of those have panned out.
