A man has pleaded not guilty to first-degree murder after admitting in an agreed statement of facts that he sexually assaulted a Calgary woman and fatally injured her.

The admission, presented by the Crown and defence, came at the opening of the judge-only trial for Christopher James Watcheston yesterday.

The 24-year-old man is charged in the death of Arcelie Laoagan, whose battered body was found near the northeast Franklin train station behind the Grace Baptist Church in January 2008.

Watcheston admitted to following the 41-year-old woman up an escalator, then physically and sexually assaulting the mother of five.

Laoagan was on her way home from working at West Canadian Digital Imaging when she was assaulted in what police called a random attack. Laoagan had come from the Philippines to Canada in 2004.

Crown prosecutor Gordon Wong told the court that he will attempt to prove that Watcheston intended to kill Laoagan.
