Christopher Dai-Ichi Yu

On March 27, 2010, Yu and Quach arranged to meet 38-year-old Tuyet Thi Huynh with the intention of robbing her under the false pretense of selling her drugs. At approximately 11:30 p.m., the defendants met the victim in a parking lot at Russell Paris Park in Westminster. Huynh approached the defendants’ car, where Quach was in the driver’s seat and Yu was in the front passenger’s seat. Huynh’s 36-year-old boyfriend, Truong Pham, waited for the victim in his car.

When the victim approached the passenger window of the defendants’ car holding cash, Yu grabbed the cash from Huynh’s hand. Huynh’s purse became tangled on the car and Huynh’s arm was tangled in the purse. Quach began to drive away and Huynh was dragged for almost a mile until she fell from the outside of the car and landed on the road. A witness stopped to help her and called 9-1-1.

The victim’s boyfriend attempted to follow Yu and Quach in his car and called 9-1-1. Yu attempted to murder Pham by shooting at his car with a firearm as he followed behind the defendants. A passing Orange County Sheriff’s Department deputy observed the two speeding vehicles and performed a traffic stop of the defendants’ car.

The deputy detained Yu and Quach, who were arrested shortly thereafter by responding officers from the Westminster Police Department (WPD). At the time of their arrest, Yu and Quach were in possession of a firearm and Huynh’s purse inside their car.

Huynh was transported to the hospital and was later pronounced dead due to head trauma from being dragged and falling from the car.

WPD investigated this case. Senior Deputy District Attorney Daniel Feldman of the Gangs Unit is prosecuting this case.
