A missing Westchester woman last seen in Manhattan was found when a Good Samaritan recognized her at LaGuardia Airport and called police, officials said.

Veronica Hallock, 24, had been missing since Tuesday when she took a Metro North train into the city without telling her family, who reported her missing.

She was last seen in security footage at Grand Central Terminal around 4:30 p.m., police sources said. The video shows her getting off the train and taking an elevator upstairs.

Hallock, who suffers from depression, was found when a person recognized her and called police.
