An older couple from Duluth and their vehicle have been missing for two days, and authorities are seeking the public's help in finding them.

Ronald Tarnowski, 82, and Mary Tarnowski, 78, were last seen about 9 a.m. Saturday, and they left their home without cellphones, police said.

Also unaccounted for is their silver 2005 Chevy Tahoe with Minnesota license plate 852JXG. The SUV has black fender flares.

Ronald Tarnowski has early-onset dementia, while Mary Tarnowski has paralysis on her right side and difficulty speaking due to a stroke years ago.

Police said in a statement that the Tarnowskis only drive to dine at nearby restaurants, and being unaccounted for "is very unlike them."

Anyone with information about the couple is urged to contact police at 1-218-730-5400 or call 911.
