Allen's body was found at 1:30 Sunday afternoon along Normandale Road, east of Missouri Route Y. The Macon County Sheriff's Department pronounced him dead on the scene.

The Missouri Highway Patrol said there were no signs of foul play. Allen had been suffering from dementia and it's possible he just wandered off.

"Six out of ten [people with dementia or Alzheimer's Disease] will wander, sometimes more than once," Pam Richmond with the Mid-Missouri Chapter of the Alzheimer's Association said.

The Alzheimer's Association exists to assist those facing a diagnosis of Alzheimer's Disease and dementia. They offer various services to help families make sure their loved ones are safe. MedicAlert Safe Return is a necklace or bracelet that has a phone number on it to contact if the person gets lost. They also encourage Comfort Zone, a Web-based location tracker, like a GPS system.

This is in addition to the personal services they offer like classes and over-the-phone care consultations. It's work Richmond is passionate about.

"The disease is kind of a light switch, you can be within a block from your home and that light switch goes off and they have no idea where they are so it's very important to take safety steps to prevent that sort of thing from happenening," Richmond said.
