The family of the young P.E.I. woman who was the lone survivor in a murder-suicide in Alberta Thursday says they're coping with the tragedy by taking things day by day.
CBC News spoke to Shayna Conway's sister, Courtney Crosby, on Sunday.
She said Conway, 21, is scheduled to be in the operating room for most of Monday.
Crosby said the family is grateful for all the messages of support.
RCMP released details of the incident Saturday.
Conway was the driver of 22-year-old Tabitha Stepple's SUV. Stepple and Conway were driving Mitchell MacLean, 20, and Tanner Craswell, 22, to the airport to catch a flight to P.E.I. for the holidays.
Derek Jensen, 21, had followed the group from Lethbridge, Alta., apparently looking for Stepple, his ex-girlfriend.
Jensen rammed the SUV, and then got out and shot the four people when they pulled over.
Jensen then killed himself, according to police.
Two other firearms were found in Jensen's car when searched by police: a loaded 12-gauge shotgun and a loaded Winchester rifle.
Conway was able to call for help and was located at the scene by RCMP where she provided a short version of what had occurred.
She was taken to hospital in Claresholm, then transferred to a Calgary hospital for surgery.
Meanwhile, family and friends of MacLean and Craswell, the two young men who died in the incident, will gather to remember them Monday.
There will be a memorial game of catch outside MacLean and Craswell's former high school in Charlottetown — Colonel Gray High School.
Participants will have the opportunity to sign a guest book. Funeral arrangements for the victims are not yet finalized.
