Court documents allege the 19-year-old was travelling at an "extremely high speed" on Ferntree Gully Road when he T-boned another car, killing 21-year-old Shannon Juriansz instantly.

The impact pushed the victim's car about 60 metres along the road where it burst into flames, a document prepared by Detective Senior Constable Morris states.
