Police have been searching for 48-year-old Wey Um who vanished during the early morning hours of March 31.
Authorities say Um was returning home from work when multiple armed men forced him into a vehicle near the 900 block of East Godfrey Avenue around 2:30 a.m.

Sources told Action News that his clothing may have been recovered along the banks of the Delaware River during a search in April.
Investigators say the men who abducted Um took off in a dark-colored newer model Ford Explorer.
The suspects were wearing dark hooded sweatshirts and were armed with handguns, police said.
"He hasn't been seen or heard from since," said John Apeldorn, president of the Citizens Crime Commission.
Um is a bartender at Oxford Tavern on Oxford Avenue.
On March 6, Um was robbed outside of the Oxford Tavern by a masked man, but it was never reported to police. Authorities have released a photo of the person of interest in that robbery, hoping it may lead them to Um.
Anyone with information is asked to contact police.
