One of the two 11-year-old girls hit by a minivan Tuesday in St. Vital remains in critical but stable condition.
Winnipeg police said Wednesday the other girl has been upgraded to stable condition.
Const. Jason Michalyshen said investigators believe the light changed as the girls crossed Bishop Grandin Boulevard at Ste. Anne's Road around 12:30.
He said it appears the van had a green light when it hit them, and that it was travelling between 70 and 80 kilometres an hour.
"It appears that they did run into traffic while the light turned green, and that vehicle that was travelling in that first eastbound lane may have not seen the girls until it was too late," he said.
"We're not looking at speed being a factor with respect to why this collision occurred, but certainly speed had an impact with respect to the injuries that were sustained."
School division puts crossing guards in place
The Louis Riel School Division said Wedneday crossing guards will be in place at the intersection where the accident happened for the remainder of the school year.
Victor H.L. Wyatt principal Tim McKay donned an orange vest and helped students cross the road.
"We're just making sure that kids are feeling safe today when they're crossing at this intersection," he said.
No charges have been laid. Police continue to investigate.
