Los Angeles police were investigating 75 cars to figure out if one of them was the getaway car involved in Wednesday's slaying of two electrical-engineering graduate students near the USC campus.
The vehicles were seen in the West Adams area of Raymond Avenue near West 27th Street. Someone walked up to a car there after 1 a.m. Wednesday and opened fire, killing Ying Wu and Ming Qu, both 23-years-old from China.
Detectives are pouring through surveillance video and have identified vehicles that match the description of a dark sedan seen leaving the area after the killings.
Police were hoping a reward of $125,000 offered by the university will lead to the killer.
"It’s the worst news that a parent could ever have,” said LAPD Deputy Chief Pat Gannon, his voice cracking with emotion during a press conference on Friday. “And I ask you, please, for your help.”
No motive was established, but police were looking at the possibility that it was a bungled carjacking, among other theories. One assailant reportedly was seen leaving the site, police said.
