Still no sign of missing Blackfoot man

The Yuma County Sheriff's Department is not ruling out that missing Blackfoot man Laurence J. "Jack" Doering, 82, may still be trying to make his way back to Blackfoot. Doering, and his wife Leah [Doering], live in Blackfoot but have been in the Yuma, Ariz., area since October.
Doering, who suffers from Alzheimer's disease, has been missing since last Thursday after he got ahold of the car keys while he and his wife were getting haircuts at a shopping plaza near Yuma. Doering took off by himself in a tan/grey 2002 Chevrolet Suburban with Idaho license plates.
"We have had some tips regarding Doering but nothing has panned out," said Captain Eben Bratcher of the Yuma County Sheriff's Department, "We are still thinking that he may be trying to get home to Blackfoot. It is not unusual for people in this condition to try and find their way home. I don't know him and I don't know what he is capable of, but I have seen stranger things happen."
Sandra Chamberlain, the daughter of Leah [Doering], contends that Doering's Alzheimer's condition is too bad for him to ever be able to find his way back to Blackfoot.
"We continue to search and hope that we find him safe," Bratcher said. "Hopefully someone will recognize him and see that he is a vulnerable adult and will call authorities."
Doering is 6 feet, 1 inch tall and weighs about 170 pounds. He has gray hair and blue eyes. Anyone with information regarding Doering can call the Yuma County Sheriff's Department at 928-783-4427 or the Blackfoot Police Department at 208-785-1234.
