PORTLAND, Ore. -- Police are searching for an 84-year-old man with Alzheimer's disease who went missing from his Southwest Portland house on Tuesday morning.
Ted Reich is believed to be driving his wife's Mercedes SUV, Portland police said.
Reich was last seen at his home in the 4900 block of Southwest Hewett Boulevard at about 11:30 a.m. Tuesday.
Reich's wife said she returned home from walking the dog and realized her husband was missing, along with her car. Reich has a history of wandering, but has never before left in a vehicle, police said.
Family members said Reich may try to head to the Multnomah Athletic Club in downtown Portland, the Portland Yacht Club on Northeast Marine Drive or the Bridgeport Pub in northwest Portland.
Reich is white, 6 feet 1 inch, 165 pounds with grey hair and hazel eyes. He was last seen wearing a red Patagonia sweater over a blue short-sleeve plaid shirt, khaki pants and tan-colored boat shoes.
He is possibly driving a silver 2001 Mercedes ML320 SUV with the Oregon license plate "GER."
Anyone who knows of Reich's whereabouts or spots him should call 911.
