Oscar L. Velasco Montano, missing since July 9 (Fairfax County Police Department)

And then on Saturday, July 9, he vanished. He was last seen at Tysons Corner, working at the office building where the Capital Grille restaurant is located on International Drive and Route 7. He did not come home.

His family was immediately concerned, Fairfax County Police Officer Tawny Wright said, and filed a missing persons report on Monday, July 11. On July 17, his family found his car across Route 7 behind the Olive Garden. There are massive amounts of surveillance video from the area to wade through, and Wright said police are doing that. Wright said Velasco Montano may have “connections” to the Hyattsville, Md., area.

Velasco Montano, 28, had two cellphones but has not used either one, family friend Jessica Cook said. There has been no activity in his bank account or credit card, either. He is originally from Bolivia, and has legal resident status, Cook said. The State Department granted his mother a special emergency visa, and she arrived Wednesday from Bolivia. He is unmarried and is not known to have a girlfriend, Cook said.

Police said they have no indication that foul play is, or isn’t, involved. Velasco Montano is 5 feet 6 inches tall and weighs about 180 pounds. Anyone with information about him is asked to call Detective John Kelly at 703-246-7826 or Crime Solvers at 1-866-411-TIPS.
