UPDATE: We're happy to report that the Fankhausers have been found.

Police in Kent County are on the lookout for a missing couple who both have severe dementia. Robert and Lucille Fankhauser left their home in Spencer Township, Mich. sometime late Sunday night.

The couple have been spotted a couple of times since. Once, they used a debit card at the Greenville Meijer around 9 p.m. Sunday, then they were seen by a gas station clerk elsewhere in northern Kent County around 10:50 p.m.

Robert Fankhauser is 87-years-old and is hard of hearing while his wife, Lucille, is 83-years-old. In the past when the couple has disappeared, they have driven as far as Ludington.

They are believed to be driving a tan 2005 Buick LaCrosse with a handicap Michigan license plate 3862F9. Their dog, a German Shepard, is also with them.

If you have any information or if you spot the Fankhausers, you're asked to please call the Kent County Sheriff's Office at 616-632-6100.
