The death of an 89-year-old Everett woman who was missing for 28 days is renewing interest in tracking systems or the Silver alert, which operates like the Amber alert in some states to find lost people who are impaired.
Washington does not use the Silver Alert but it has an Endangered Missing Person Advisory Plan. Washington State Patrol spokesman Bob Calkins told The Daily Herald it's underused.
Ethel O'Neil was in the early stages of dementia when she disappeared July 16 while driving to the Everett Mall, just three miles from her home. Her body was found in her car Tuesday in bushes near Lake Stevens.
Search and rescue experts say people with Alzheimer's disease or brain injuries should wear traceable bracelets.
