HOUSTON – Investigators need your help finding a man caught on surveillance video taking cash from a register at a southwest Houston convenience store. It happened on September 25 around 10:15 a.m. when police said an unidentified man walked into the store on S Braeswood off Southwest Freeway. From there, the man went up to the employee behind the counter and showed a handgun. The video doesn’t actually show the man’s gun but him brandishing something under his shirt insinuating he has one.
