Five-and-a-half years after the disappearance of a Saskatoon woman, authorities say a suspect now charged in her murder walked into a police station and told them where to find her remains.

Nearly three weeks ago, police say Jerry Franklin Constant, 33, allegedly told them what happened to 20-year-old Karina Beth Ann Wolfe, and pointed them in the direction of a marshy area near the city's airport.

Following a four-day search, Wolfe's remains were found hidden among trees and brush.

Police say they believe the 20-year-old's body has been there since July 2010.

Wolfe was last seen getting into a car in front of her mother's home in Saskatoon that year.

"The last memory I have is Karina saying: 'I love you mom and I will be home later," Wolfe's mother, Carol, told CTV Saskatoon.

Constant appeared in court on Monday on the charges of second-degree murder and offering an indignity to a body.

Police say Wolfe and Constant did not know each other, and he was not a suspect before this month.

The court heard Monday that Constant told police on the day of his apparent confession that he was hearing voices, and he is scheduled to undergo a psychiatric assessment.

"There may be some issues with his fitness to stand trial," said Crown prosecutor Matthew Miagza.

Carol Wolfe described her daughter as a talented artist, painter and journalist, and her family is now planning a funeral.

"I'm grateful that she was returned home so family can lay her to rest," said Carol Wolfe.
