A 61-year-old Ashburn man has been reported missing. Sun Kun Chang was last spotted around 4 p.m. and is believed to be traveling in a white Acura RDX.
The Loudoun County Sheriff's Office is asking the public for help locating Chang, according to a Facebook post from the Loudoun County Sheriff's Office that labeled the case “missing and endangered.” Anyone with information is asked to call 703-777-1021, a number that connects directly to dispatchers at Loudoun County's Emergency Communications Center around the clock, according to Loudoun County.
Dulles Landing Drive sits inside the Dulles Landing shopping center, a sprawling retail hub near the intersection of U.S. Route 50 and Loudoun County Parkway that anchors stores including Walmart, HomeGoods, and Dick's Sporting Goods, per The Burn. The shopping center is in southern Loudoun County.
How Virginia Classifies an Endangered Adult Case
Deputies labeling Chang's disappearance as endangered points to specific state criteria. Under Virginia Code § 52-34.10, a Critically Missing Adult Alert can be activated for anyone 18 or older whose disappearance poses a credible threat to their health and safety as determined by law enforcement, according to Virginia State Police regulations. That framework is distinct from the state's Senior Alert Program under Virginia Code § 52-34.4, which applies specifically to missing adults over 60 who suffer from cognitive impairments such as Alzheimer's disease or dementia that leave them unable to care for themselves without help.
Local agencies use the Virginia Criminal Information Network and the National Crime Information Center to record identifying and descriptive data. The response can also include public alerts.
A Difficult Stretch for Loudoun County Searches
Chang's disappearance comes after recent missing-person appeals in Loudoun County. In late August and early September, the sheriff's office issued appeals for two 81-year-old Purcellville residents, Carolyn Taylor and Raphael Dadzie. Raphael Dadzie was the subject of a missing-person appeal, according to WUSA9. Hoodline covered both cases, including the appeal for Raphael Dadzie and the earlier Carolyn Taylor disappearance.
The sheriff's office has issued missing-person notices. Loudoun County has also grappled with missing-person cases before.
The available information does not address any broader regional alert for Chang's vehicle. Anyone who has seen Chang or the white Acura RDX is urged to contact the Loudoun County Sheriff's Office.
