Carly Bragnalo was killed Thursday in a crash in Jamaica, where she was on holiday. She was 27.
"Today the Canucks lost a member of our family," Canucks general manager Mike Gillis said in a statement. "Carly was a lovely and generous young woman who shared her spirit for life with our players, their spouses and their extended families. We will support the Bragnalo family, Taylor and his entire family in any way we can during this very difficult time."
The couple was to be married this summer.
In a statement, the Pyatt family said it was "deeply saddened by this tragic loss.
"At this difficult period, the family would request to be given the time to grieve in private. We are focused on our son and the Bragnalo family. We thank you for your support and understanding."
It's the second time in less than a year that tragedy has struck the Canucks. Last May, promising young defenceman Luc Bourdon was killed in a motorcycle crash in New Brunswick.
