All three drivers have been found, but there's no word yet if charges will be laid.
Police have identified those involved in the fatal hit and run on the QEW in Beamsville.
Twenty-eight-year-old Adam Cherrie of St. Catharines was hit several times after his S-U-V was in a one-vehicle collision near Ontario Street, early Tuesday morning.
Cherrie's vehicle crashed into the centre median and he was hit while outside his vehicle.
The OPP says there were looking for two trucks and a silver or gold Hyundai or Kia with front-end damage.
That area of the QEW was closed for 10 hours.
Police continue to investigate and are looking for witnesses.
