REGINA -- A security guard has testified at an inquest that he found people wandering the Conexus Arts Centre before on the main stage or in the theatre, but never someone who climbed up to the catwalk.

The inquest is looking into the case of 17-year-old Jaidan Slaferek, who died in a 12-metre fall on Jan. 15, 2012.

It has been told that procedures at the Regina arts facility have been changed since the girl's death.

Brian Stubbings says he was posted that night at the security staff entrance behind the stage.

He was turning off the house lights above the seats when he heard sounds coming from near the darkened stage.

He went to see who was there and found two panicked young men on a stairwell backstage, but it wasn't until he turned on the stage lights that he fully realized what had happened.
