UPDATE: Henderson was found this morning, and reunited with her family.
Hershenson's whereabouts have been unknown since about 9:30 a.m. Monday. Worried loved ones are asking you to keep an eye out for her. News about the missing persons case has spread like wildfire among journalists, perhaps due to time Hershenson spent as a a press secretary on the Hill.
Reached by phone this evening, Herchenson's husband Tom Hershenson said his wife's morning route included walking from the area of 18th Street NW and Columbia Road to the Woodley Park Metro Station, where she'd catch the Red Line to Bethesda. He's putting together clues as they come in.
He said her last credit card purchase was at a Starbucks (he believes it was the one located at 1801 Columbia Road NW) and that last night, at about 8:30 p.m., a woman thought she saw Hershenson on the northbound 42 Metrobus. Since then, the most solid clue as to Hershenson's potential whereabouts has been that her SmarTrip card was used to board a bus at Georgia Avenue and W Street NW this afternoon.
"We're worried about her," said Tom Hershenson, voice breaking.
Hershenson is 33, approximately 5′ 7″ and 150 pounds. She was wearing jeans, a purple shirt, and a sweater when she disappeared. If you spot her, please call 202-680-4181 or notify the Metropolitan Police Department.
