Winnipeg Police have confirmed that a body discovered in the Red River on Saturday is that of Lisa Gibson, the mother of two young children who died after being found injured in the family’s home earlier this week.

Gibson, 32, had been missing since Wednesday when her three-month-old son and two-year-old daughter were found critically injured in a bathtub in their home. They were rushed to hospital but did not survive.

Gibson was the last person to be with the children, named Nicholas and Anna. Earlier this week, police said Gibson was a "person of interest" in the case but stressed that authorities were primarily concerned for the woman's well-being.

A group of paddlers discovered Gibson’s body in the Red River on Saturday morning, several kilometres downstream from her family home near the Assiniboine River in Winnipeg's west end. The Assiniboine empties into the Red River.

Police have completed an autopsy, but said the results are not public.

“At this point, that information won’t be made public,” Winnipeg Police Const. Eric Hofley told reporters.

"The results of those autopsies have to be fully looked ... to determine if perhaps there are some other explanation as to the cause of this incident."

He added that the investigation remains open.

"There's been a lot of speculation out there in the media and in the public, however investigators have to ensure that every possible avenue has been followed up.”

Police wouldn't publicly comment on whether post-partum depression could have played a role in the case, but a source told CTV News that Gibson was struggling with the condition.

Gibson’s family has asked for privacy while they deal with their loss.
