Six members of a Vietnamese gang have been charged with murder in a shoot-out at a Garden Grove restaurant two years ago that left two people dead and four others injured. Three of the suspects were arrested in Orange County. The others were already in custody in Los Angeles County on unrelated charges, police said. They were charged in connection with the Nov. 17, 1985, shoot-out at My Nguyen Restaurant. Investigators determined that the shootings occurred after a dispute that took place earlier in the restaurant between one of the victims and a gang member. The suspects were charged with two counts of murder and one count of conspiracy to commit murder, police said.
