38-year-old Allan Shyback has been charged in connection to the death of his common-law wife who was reported missing in October of 2012.

On Friday, a search warrant was executed at the Ogden residence where Lisa Mitchell lived at the time of her reported disappearance. Police located human remains inside the home located on 26A St. S.E.

Shyback, Mitchell's common-law husband, was arrested at a location outside of Calgary in connection to the search. The 38-year-old has been charged with second degree murder and indignity to human remains.

Mitchell's two children, aged 7 and 5, continued to live with the suspect at the Ogden home following Lisa's disappearance. The suspect is the biological father of one of the children.

“The kids are one of our primary concerns and that’s why we’ve been very careful with discussing these matters,” said Sgt. John Hebert of the CPS Missing Persons Team. “They are being taken care of at this time, but obviously they’re going to need additional resources a later.”

The search was conducted at a time when CPS members were certain the children were not in the home.

The Forensic Crime Scene Unit continues to investigate the residence and the Medical Examiner has been notified. An autopsy is scheduled for Monday.

Sgt. Hebert says Lisa's mother is aware of the arrest.

“I went out and notified her yesterday of the developments,” said Sgt. Hebert. “I think she took the news with a measure of grace considering what the news was.”

According to one neighbour, name withheld, Mitchell's husband and two children lived in the suspect home. The neighbour says they have had a chilling encounter with Mitchell's husband since Lisa's disappearance, and describes the husband as 'off'.

31-year-old Lisa Michelle Mitchell's last known whereabouts was at the Ogden home on October 29, 2012. She was reported as missing the following month.

Police say they had responded to the home prior to Lisa's disappearance following reports of a domestic incident. No charges were laid in connection to the investigation into the event which police referred to as minor.

Shyback is expected to appear in court on Monday, December 8.
