To the family of Denise Nashiro, please get her a personal GPS device to locate her the next time she wanders off. Modern GPS units are small pager-size units which can fit in a pocket. You can locate your loved one with your smartphone or computer using maps similar to Google Maps.
Check out these two sites for devices that work. You can search the internet for other devices.

I hope she is found safe.
