BEHAVIORS OF MISSING ELDERLY PERSONS

From Project Jason comes this article about missing elderly, focusing on those with Alzheimer's or dementia (neither of which apply to Jack Gordon). 

Brad Dennis, Director of Search Operations for the KlaasKids Foundation, outlines typical behaviors exhibited by a missing person with Alzheimer or dementia:
• Usually (89%) found within one mile of the Point Last Seen (PLS), half found within 0.5 miles.
• Subject usually found a short distance from road (50% within 33 yards)
• Subject may attempt to travel to former residence or favorite place.
• Subject will not leave many physical clues.
• Will not cry-out for help (1%) or respond to shouts (only 1% response rate).
• Succumbs to the environment (hypothermia, drowning, and dehydration).
• They go until they get stuck.”
• Subject usually found in a creek, or drainage and/or caught in briars/bushes (63%)
• Leaves own residence or nursing home, possibly with last sighting on a roadway. May cross or depart from roads (67%).
• Coexisting medical problems that limit mobility are common.
• Has previous history of wandering (72%)
• They appear to lack the ability to turn around.

These patterns formed the basis of our initial searching for Jack.  Since his vehicle was found at the home site, we focused on the area within 3/4 of a mile from the site.  Our initial thinking was that Jack had suffered a medical event of some kind.  Multiple searches over the next week did not turn up any sign of Jack. He did not turn up wandering along the road. He did not turn up at the local hospital.
