Yellowknife RCMP have confirmed that a body found Tuesday in Yellowknife near Frame Lake was that of a missing 15-year-old girl, Cassidy Giroux.

Giroux was reported missing by her family on Monday, and RCMP sent out a news release that evening. It said she was last seen Friday evening.

Police first learned about the body at approximately 9:15 a.m. Tuesday and initially called it a sudden death.

"At this time, although a postmortem examination has not yet been completed, investigators do not suspect any criminality is involved," a statement Tuesday afternoon said.

RCMP said Yellowknife Ground Search and Rescue, as well as the Civilian Air Search and Rescue, were searching for Giroux, both on the ground and in the air late into Monday evening.

In response to questions from CBC, RCMP said in an email that it had "received information indicating that Cassidy may have been near a lake."

The search resumed first thing Tuesday morning, when RCMP say they learned that one of the search teams had found a body off the Frame Lake Trail, between Matonabee Street and Albatross Court.

"Our thoughts are with the family, friends, classmates, and all those affected during this difficult time," RCMP said in the statement.

RCMP spokesperson Cst. Heather Cosenzo reiterated that no foul play is expected, but would not expand on that due to the investigation. She said a toxicology test will be completed on the body.

"Although we do not have any indicators that alcohol was a factor," Cosenzo said in an email.

She said they're still putting together a timeline of events leading up to Giroux's death.

Student at St. Pat's

Claudia Parker, the superintendent for Yellowknife Catholic Schools, says Giroux went to École St. Patrick High School.

"She was a new student at St. Pat's this year. A nice young lady," Parker said. "I haven't had the privilege of meeting Cassidy myself."

"We're just focusing on what do we need to do to support our students at the school, and any staff at the school who are dealing with the loss."

Parker said their crisis response team has been contacted and supports are in place for staff and students, with counsellors available.

"I think it's very sad," she said. "It's a tragic event and it's heartbreaking to see a youth lose their life at such a young age. And basically our condolences go out to the family. And our prayers are out to the family."

Parker said the school board is considering a celebration of life for Giroux next week, if the girl's parents approve.
