A 29-year-old Okotoks man is facing numerous charges including impaired driving causing death in connection to a fatal crash in Erin Woods last September.

An 11-year-old girl died when the minivan she was riding in was broadsided by a Ford 150. A 53-year-old man and 40-year-old woman also suffered serious injuries.

Police say the driver of the truck ran a red light.

"Following a lengthy investigation by the CPS Traffic Section, investigators allege the truck’s driver was impaired by alcohol and was speeding," said police in a release.
