An Oakland family is getting more concerned by the hour. Their father, who suffers from dementia, has been missing since Tuesday afternoon.
Robert Lichtenstein, pictured above, went out on a walk Tuesday at 3 p.m. wearing a dark brown jacket, dark pants and white shoes. He hasn't been seen since. He was last seen on the 4200 block of Gregory Street.
Lichtenstein is 90 years old and normally uses a walker to get around. He answers to the name Robert or "Bob."
His family has spend the week posting flyers and asking people to help look for him.
