One minute was all it took for James Gargasoulas to inflict a trail of destruction and horror along Bourke Street on January 20 last year.

Less than one hour was all it took on Tuesday for a Supreme Court jury of seven women and five men to find him criminally responsible.

In the 22 months in between, Bourke Street survivors and the families of 33 pedestrians mowed down by a stolen maroon Holden Commodore quietly waited as Gargasoulas fronted a series of court hearings, including two which focused on his fitness to stand trial. The second of those, last month, found he was.

After all the waiting, some family members on Tuesday wiped away tears as the jury foreman said "guilty" 33 times before a packed court, finding proven the six charges of murder and 27 counts of

reckless conduct endangering life.
