A 61-year-old Ohio tourist with Alzheimer's disease who disappeared after leaving a midtown Manhattan hotel has been found safe, police say.

Vivian Minnielli, of Hamilton, Ohio, was found on a park bench on the Upper West Side Monday evening, according to police. A passerby recognized her from media reports and contacted authorities.

She was in good condition.

Minnielli had been last seen at the New York Hilton Midtown hotel on Sixth Avenue at about 3 p.m. Sunday, police said.

Her relatives said she was seen on surveillance video walking out the front door of the hotel and heading north, perhaps toward Central Park. She was not carrying identification, they said.

The couple traveled to New York City with their granddaughter, Samantha.

Relatives said she was diagnosed with Alzheimer's about three years ago.
