The chase ended a short time later on Monterey Road in San Marino, when the Nissan went out of control while negotiating a 90-degree corner and crashed against a curb. Investigators said the vehicle was pinned in place by a Thunderbird driven by DEA agents who smashed into the Nissan's rear end, flattening the back of the car.
Officials said an intense gunfight erupted, and agents killed the Nissan's driver and a passenger, one of whom was Kow.
One of the dead suspects was described as a 26-year-old Monterey Park resident, according to coroner's investigators. The other dead suspect was carrying several different identification cards, according to a coroner's spokesman.
A third suspect, seated in the back of the Nissan, was in serious condition with gunshot wounds at County-USC Medical Center, officials said.
Police also apprehended a second group of suspects in a black Mitsubishi, which sped away from the first shooting scene and went to Monterey Park. One woman and two men in the car were arrested, police said.
None of the other suspects' names were released by investigators, who said to do so would hamper their inquiry.
