ALHAMBRA – A 19-year-old Rosemead man was ordered Friday to stand trial for the murder of an El Monte man and the attempted murder of another man. After a four-day preliminary hearing, Alhambra Superior Court Judge Frederick R. Rotenberg determined he had heard sufficient testimony and evidence to hold defendant David Do for trial on murder and attempted-murder charges. Also facing the same charges stemming from the drive-by shooting in December is 19-year-old Garrett Quon of San Gabriel, although Deputy District Attorney Martin Bean has said that authorities believe Do was the triggerman. Quon is scheduled to appear in the Alhambra courthouse on Thursday, when he will receive a date for his preliminary hearing. Both men have pleaded not guilty and remain held without bail. Before his trial, Do will be arraigned Sept. 24 in Pasadena Superior Court. He is charged in the murder of 18-year-old Nhi Gip of El Monte and the attempted murder of another man, age 19, whose name was being withheld by authorities to protect him from retaliation. The wounded man spent more than a month in the hospital recovering after being shot three times. He testified against Do at the defendant’s preliminary hearing and also identified Do in court as the gunman. Authorities believe the shooting was related to a rivalry between Asian gangs. Several witnesses testified in court that they saw Do riding in the front passenger seat of a white car that pulled up to a group of teens at a coffee shop in the 300 block of Valley Boulevard about 11:30 p.m. Dec. 1. The witnesses testified they saw Do lean out of the car’s window and yell to the crowd, asking which gang they belonged to. The wounded 19-year-old yelled back that he did not belong to a gang, he testified. Seconds later, shots rang out, hitting Gip and the other man. Gip died at the scene, investigators have said. An 18-year-old Rosemead woman who witnessed the shooting – and whose name also was withheld – testified that she heard a male voice yell, “Wah Ching,” the name of an Asian gang, just before shots were fired.
