"I found the lady and her face was smashed in quite badly," a court has heard.
Clive Carter, 35, from Motherwell, denies murdering Khanokporn Satjawat, from Thailand, by battering her on the head and body with a fire extinguisher at the Clyde Auditorium, on November 12, last year.
He has admitted killing the 42-year-old but claims he was suffering from diminished responsibility at the time.
Yesterday, at the High Court in Glasgow, steward Karen Daly, 36, said Carter walked past her, looking "pale" and told her he had found the victim.
The jury heard that just before Miss Satjawat's death, Carter was complaining of fatigue due to long working hours. The court was told that between June and July, last year, Carter worked for 26 consecutive days.
And he worked a total of 24 hours on the Saturday and Sunday before Miss Satjawat's death.
The trial continues.
