A 49-year-old Newfoundland man has been found guilty of killing his roommate on New Year's Eve, 15 months ago.

William Tubrett was convicted of manslaughter Thursday in the death of Jamie Vickers after three weeks of evidence and 10 hours of deliberation.

The jury rejected the charge of second-degree murder, even though the foreman told the judge that the jury didn't believe Vickers was killed in self defense.

Earlier in the trial, Tubrett testified Vickers woke him up in the middle of the night furious about the messy kitchen.

He claimed Vickers was "pounding on him" and, "I was doing anything to save myself. Natural instinct just took over."

The medical examiner told the jury Vickers, who weighed about 250 pounds, was strangled.

Vickers' family cried softly in the courtroom as the verdict was delivered.

A sentencing hearing will be held Friday afternoon.
