FRIENDS of an innocent teenager killed when caught in the path of street-racing hoons were the first to get to the horrific scene.
The Riverland youth, 17, was killed while innocently turning into the path of two racing cars at Park Holme.
"It's not a scene you see everyday," said Richard Beech.
"We just headed out there hearing an accident had happened. To find out it was friends was shocking".
The crash happened about 10.40pm at the intersection of Pildappa Ave, and Marion Rd.
The innocent victim, driving a Mitsubishi sedan, was turning right and was hit by a Commodore sedan, one of two vehicles speeding north on Marion Rd.
A black Nissan Sylvia involved in the race failed to stop at the scene of the crash.
Major Crash Investigators are appealing to the driver of the Nissan to come forward.
Two passengers in the Mitsubishi sedan and two occupants of the Commodore, including the driver, 24, were taken to the Flinders Medical Centre and are expected to survive their injuries.
Anyone who witnessed the crash is asked to call BankSA Crime Stoppers number on 1800 333 000.
