Investigators say Garfinkle was hit and tossed on top of the hood of the car. They say upon impact the driver stopped, a passenger got out, dragged Garfinkle off the hood and tossed him to the ground. The passenger then got back into the car and the driver took off, leaving the victims at the scene.
Both students were taken to California Hospital Medical Center, where Bachan died of massive head trauma.
Adrianna's mother, who is overwhelmed with grief, spoke out Monday morning.
"She was unbelievable. She was good," said Carmen Bachan, Adrianna's mother. "I don't even have tears I've cried so much. I don't have tears. I want my daughter."
Garfinkle remains in stable but serious condition after undergoing surgery. He reportedly suffered broken legs and a broken arm.
For Carmen Bachan, the sheer brutality of the crime is incomprehensible.
"They're pigs. They ran the light, took my daughter and the young man that was with her, and when he hit the windshield the [passenger] got out of the car and threw him on the street and left my daughter dying," said Mrs. Bachan.
One of the victims' friends says the two were headed back to their rooms when they were hit.
"You know, just doing something they normally do and unfortunately they were at the wrong place at the wrong time," said the friend.
USC students and members of the Greek community are alarmed.
"The fact that the car stopped like 500 feet up from the intersection and pulled the individual off the hood and then kept going, I hope they catch them and bring them to justice," said USC student Geoff Larson.
The vehicle is described as a black or charcoal Honda Accord, Lexus or Toyota Corolla. Detectives say the car has extensive damage to the hood and a broken windshield.
Police say they need the public's help to solve the crime. Anyone with information about the car or driver is asked to call the Los Angeles Police Department at (877) LAPD-24-7.
A makeshift memorial has been set up at the intersection where the incident happened.
