Family members of two young people killed on their way home by a speeding car from a Justin Bieber concert in Vancouver three years ago say they cannot believe the driver was found not guilty of dangerous driving causing death.

Andelina Hecimovic, now 26, was charged with two counts of dangerous driving causing death after Johnny deOliveira, 21, and Beckie Dyer, 19, were killed when the Toyota driven by Hecimovic skidded, flipped over and slammed into their Suzuki Swift in Pitt Meadows, B.C.

"Their lives were worth something. She can walk and breathe and get married and have babies and we don't get that. We will not ever see that," says Audrey deOliveira.

At the trial earlier this month, crash investigators alleged Hecimovic was driving aggressively on the night of the crash.

But Hecimovic testified she was distraught because of events at work that night and failed to see the lights at the intersection through her tears after making a lane change.

But speaking outside the courtroom on Wednesday, the victims' families said they didn't buy Hecimovic's defence, saying the verdict sends a dangerous message to drivers.
