A portion of a 911 recording played at the murder trial of Nicholas Rasberry, who stands accused of killing Craig Kelloway in May 2013.

During the 12-minute 911 call made after 11 p.m. MT, Rasberry tells the operator Kelloway is gasping for breath and making gurgling sounds.

She asks him to clear the victim's airway.

"I'm looking in your mouth," Rasberry can be heard saying to Kelloway. "I f--king hate you."

Near the end of the call, once the police are on the line and officers and paramedics have arrived at the house, Rasberry can be heard saying: "I didn't do anything wrong .… I was attacked."

Kelloway, a teacher from Nova Scotia, had been in Calgary for six years and left behind a six-month-old son at the time of his death

The trial is scheduled to last up to four weeks.
