A mother and three children from Tisdale, Sask., were found slain and police say a suspect in the killings has also been found dead.
Police haven't released the names, but family members have confirmed the woman who died is LaTasha Gosling, 27.
Her children include two girls, Janyaa, 4, and Jenika, 8, and a boy, Landen, 7, who have the same surname.
Police made the grim discovery in a mobile home around 1 a.m. CST Wednesday in the east-central Saskatchewan town.
The male suspect was tracked to a home in Prince Albert and when police entered the premises at 6:20 a.m, they found him dead, RCMP said.
Baby found next to body of man
Police would not say how the man died, but said his death was not a homicide.
A six-month-old baby was found with him. The baby is now being cared for by family.
There were two other adults in the house where the man's body was found, but they won't be charged, the police said.

Police did not provide the relationship between the man and the woman, but said they were known to each other.
The woman and her children had been reported missing the day before.
'Hard-working young family'
A woman who along with her husband owns Wicks' Mobile Home Park on the north side of the town, said a young couple and children had been staying there. Police confirmed that's where the woman and three children died.
"I believe it was in one of my trailers cause right now as I look — I have a store right across from there — and I can see several police cars sitting there with yellow tape around the trailer," said Laurie, who didn't want her last name published.
She described them as a "hard working, young family" and said the father had recently been laid off from his job in the Alberta oil patch.
"They were very quiet and I had no problems with them at all," she said. "They were very good, very quiet. No neighbours complained about them."
