Surveillance video from a jewelry store in DC shows the moment an armed robber pulled a gun on the shop owner in June. News4's Jackie Bensen explains how it could now help solve the murder of another jewelry shop owner in Arlington.
D.C. police are trying to determine if the man seen in a security video of a June 9 jewelry store robbery in northwest Washington is connected to a murder at an Arlington jewelry store over the weekend.
Police say surveillance video of the Arlington robbery at Capital Jewelers on Columbia Pike shows it was committed by a person wearing a yellow traffic safety vest -- a possible cover, since many construction workers in the area wear the vests as they work.
Tommy Wong, 52, of Herndon, was killed in the robbery.
Video released from the June 9 robbery in Northwest also shows a gunman wearing a yellow safety vest. Arlington police interviewed the victim of that robbery Monday morning.
