It appears Elizabeth and Liam had been walking home from the Capital along the side or the motorway that night, but today her friends said they couldn't understand what had happened.
One driver told the Evening News of how he swerved to avoid the teenager after she had been hit by the minibus and the car.
The motorist travelling behind the car that hit her, who asked not to be named, said he swerved to avoid her body as it landed in front of his vehicle.
The 38-year-old said: "I was driving along westwards when the car in front seemed to hit something. It was pitch dark so I only knew about it because the car's tail-lights seemed to jump up into the air a little. I thought the car had hit a fox or a dog.
"When my lights caught it, I realised it was a person's body and managed to swerve round it. The driver behind me also struck her body and several lorries and other vehicles coming behind also ran over her.
"I pulled up to the side of the road, as did other drivers who had been in front and behind me. The other drivers who stopped where all shocked by what had happened."
Ambulance crew pronounced her dead at the scene and the road was closed in both directions for around six hours.
Police are now appealing for witnesses to the crash to come forward as they try to piece together what happened.
Inspector David Milne, from the force's road policing unit, said: "We are considering the possibility that other motorists may have hit the victim as they travelled west on the M8 at around 11pm, after the initial fatal collision.
"They may have been unaware of striking her at the time, but may now suspect otherwise. If so, we would also urge them to get in touch."
