Jerry Constant, 33, is the man charged in the death of Karina Beth Ann Wolfe. Police announced on Friday that Wolfe’s body had been found after she went missing in 2010.

Her remains were found in a field Nov. 14 after police received a tip that led them to that location.

Constant has been charged with second degree murder, and offering an indignity to human remains in connection with Wolfe’s death. He made his first court appearance on Monday. Wolfe’s family was at court for his appearance.

Police also held a news conference Monday morning and released new details about the case.

Police say Constant was the tipster who led them to Wolfe’s body. They say the body has been in the same place since July of 2010. They also revealed that Constant and Wolfe met on July 2, 2010, they were not known to each other before that.

The Crown has asked for a psych assessment saying Constant’s behavior was “erratic” when he went to police with information about the case. The Crown says Constant told police he was hearing voices.

Constant has a criminal record. He’s been convicted of assault, unauthorized possession of a prohibited or restricted weapon, among other things. He was ordered to be placed on the national sex offender registry in June of 2005.

Documents show in May of 2012, Constant was charged with and pleaded guilty to failing to comply for not notifying officials of a change of address.

On Feb. 17 of this year, Constant was acquitted of sexual assault by a trial judge. The victim claimed Constant sexually assaulted her in Dec. 2011, he argued that it was consensual.

Constant has also gone by other names, including Jerry Mitchell and Steven Franklin Sewap.

Wolfe’s relatives have held yearly vigils to remember her and to raise awareness of missing and murdered aboriginal women. Her disappearance was considered suspicious by police because she lived what they described as a high-risk lifestyle.

Her mother said Wolfe got into a grey Corvette in front of her Saskatoon home back in 2010. Police were able to determine the young woman was later dropped off and was last seen in front of a phone booth.

In July 2014, on the fourth anniversary of Wolfe's disappearance, her family led an emotional march that started at the spot where her mother last saw her.

Josephine Longneck, Wolfe's grandmother, said at the time that the family hoped the vigil would make the public take notice of missing persons cases.

"It isn't just Karina that went missing. This is a daily thing where aboriginal people are missing," she said.

Wolfe's mother, Carol, said at the same vigil that she would never stop looking for her daughter.

"The last time I saw ... I asked Karina if she was coming home that evening and I told her that I loved her."

Constant will be back in court in December 8.
