Skye Buck and his wife Courtney, who were both 30, were killed Sunday when their car skidded off an icy patch of Highway 5 and plunged 30 metres down an embankment into the North Thompson River, north of Kamloops.
Kamloops-Thompson School District Superintendent Terry Sullivan said the couple will be sorely missed.
"It's a terrible tragedy and we are struggling now to extend the depths of our sympathy for the family (and) for the community," he said.
A friend of the couple, Lenka Moravcova, said Skye Buck had told her recently his wife was seven months pregnant.
"He said that he's expecting a little one shortly after Christmas in the New Year (and) we were joking that he should volunteer for the Davis Cup if they happen to have (the baby) in Vancouver, and he said it will be very difficult because they will have a newborn," she said.
Skye Buck was a basketball player who played professionally in Europe before becoming a math teacher at Clearwater Secondary.
Courtney was a Grade 1 teacher at Raft River elementary school in the town.
RCMP Constable Leslie Smith said the deaths have shocked the community.
"They were prominent, well known throughout the whole Clearwater community,and it's just such a tragic event at this time, and the entire community of Clearwater is grieving."
Sullivan says a critical response team has been sent to Clearwater to help students and staff at the high school and elementary where the two taught.
Skye Buck would have turned 31 on Tuesday.
