Tong Van Le, 44,owner of Nasser Market in Bernal Heights and father of two, was murdered at his Novato home on Saturday. The widely assumed reason, according to SFPD, is because he testified against two suspects who robbed his store a month earlier. Police think that Le may have been followed home from his store to his house by the assailant(s). No arrests have been made. Earlier this year, if you recall, Justin Lee, 40, was gunned down on 26th Street after leaving his witness protection program safe house. (SFGate)
