A 70-year-old woman who went missing on Jan. 2 was found in Arlington Central Library last night, according to a source familiar with the situation.

Buckingham resident Julienne Erisnor, 70, was located just hours after Arlington County Police issued a press release asking for the public’s help in finding her. Quick-thinking library staffers spotted Erisnor in Arlington Central Library (1015 N. Quincy Street) and immediately called police, we’re told.

Police came to the library and Ms. Erisnor was reunited with her daughter.
