Pasco police are scouring the video footage from the 7-11 surveillance cameras at 14th and Sylvester after a lone gunman held up the store late Sunday night.

According to reports, the man, dressed all in black with a black ski mask,  brandished a semi-automatic pistol, demanded money from the clerk, and fled-apparently on foot.   The clerk said he was about 5'6" but little else was known.    The public is encouraged to report any information to Tri Cities Crime Stoppers.  Anonymous tips are welcome.
