Family pleads for help finding 78-year-old Quang Hang, who vanished after leaving Chantilly for a car repair

The frantic search for 78-year-old Quang Hang has stretched into its sixth day, his daughter and a growing circle of neighbors and volunteers combing roads and parks after the small-framed grandfather disappeared the afternoon he left home to take his car to a mechanic. “He has not taken his medicine since Monday. He is missing five doses. We are incredibly concerned for his safety, for his health,” his daughter, Betsy Hang, says, and those words have become the rallying cry for the community trying to bring him home.

According to family accounts and law enforcement releases, Hang drove away from his Chantilly home around 2:30 p.m. on Monday, December 1, in a 2007 red Toyota Camry (license plate KGN6811) bound for a Leesburg repair shop — but he never arrived. Surveillance footage later placed him at an Aldi supermarket in Chantilly that afternoon, wearing the clothes shown in the images Fairfax County police released.

Investigators and the family have tried to piece together a confused trail: police say a traffic camera captured the Camry on the George Washington Parkway near Slater’s Lane at about 4:50 p.m., and an AirTag on his key chain later pinged in Lorton on Old Colchester Road roughly forty minutes after that. After those signals, recorded locations go cold. Betsy Hang believes her father—who suffers from memory loss—made a wrong turn and began heading away from Leesburg, disoriented and vulnerable as night fell.

Hang is described as about 5 feet 2 inches tall and 125 pounds, a small-framed man who walks slowly and needs blood-pressure medication he hasn’t taken since Monday. He speaks English as well as Vietnamese and Cantonese; family members worry he might be drawn to neighborhoods, businesses, or places of worship where those languages are spoken, so searches have included locations where local Vietnamese and Cantonese speakers gather.

Fairfax County police and local volunteer networks have coordinated door-to-door canvassing, social-media alerts and phone trees. The department posted images of Hang and his vehicle and asked anyone with information to call Fairfax County Police at 703-691-2233—or 911 if they believe there is immediate danger. Community groups have organized search teams to check wooded areas, commuter parking lots and stretches of road between Chantilly and Lorton.

Small, practical details have mattered: neighbors have driven the likely routes between the mechanic, the Parkway and Old Colchester Road; volunteers have checked under bridges, in culverts and at park trailheads where an older, confused person might stop and sit; local businesses have been handed posters with Hang’s photo and car description. The family’s tone mixes pleading and sharp practicality—asking people to look for the car, for Hang on foot, and for any sign of disorientation.

There are a host of heartbreaking what-if questions that keep coming up at search briefings: Did he stop at a gas station? Did he try to ask for directions and get turned around? Did the AirTag’s final pings show the car parked or in motion? Investigators say they are following leads, but so far the most reliable help has been the public’s eyes: one credible sighting can change the search plan overnight.

Betsy Hang and volunteers are asking anyone who was in northern Fairfax or along the GW Parkway on Monday afternoon and evening to check dashcam footage, doorbell video, and to re-check camera files from businesses along likely routes. The family’s message is simple and urgent: if you see a man matching Quang Hang’s description, or a red 2007 Toyota Camry with plates KGN6811, call Fairfax County police at 703-691-2233. Every tip matters; every minute counts.

If you have any immediate information, please contact Fairfax County Police—this community is mobilized and waiting to bring a 78-year-old father and grandfather safely back to his family.
