The boyfriend of a missing Fort Saskatchewan woman was released from custody just days before she disappeared.

Court documents show Mark Lindsay pleaded guilty on Aug. 12th to assault with a weapon for stabbing Dana Jane Turner in the head on June 22, 2011.

Lindsay was sentenced to 50 days in jail but was released after being given credit for time already served.

Turner, 31, was last seen around 5 p.m. on Aug. 14 when she was caught on security video at a west Edmonton gas station. Earlier that day, she was seen leaving the Quality Inn West Harvest on Stony Plain Road with an unknown man.

Turner's mother, Wendy Yurko, is frustrated that RCMP will not tell her family who they believe he is.

"We only know that they said it would compromise the investigation," she said. "Sometimes I sit here thinking I will wait forever and not know what happened to her."

Lindsay is now in custody in Kamloops B.C., charged with robbery and possession of a weapon in a non-related case. Details of that arrest are under a publication ban.

Sources tell CBC News that Lindsay is the adopted son of former Edmonton Police Chief John Lindsay.

Lindsay is currently a deacon at a Roman Catholic Church in Edmonton. He has not been available for comment.
