Michael Robert Bryenton was found guilty of assault causing bodily harm, but not guilty of the more severe charge of aggravated assault.

In Charlottetown Provincial Court on Friday, Judge John Douglas said he could not say beyond a reasonable doubt that the 36-year-old punched Trevor Acorn, as Acorn and the crown alleged.

The defence argued during trial that while Acorn was assaulted at a Euston Street boarding house last November as a result of a drug dispute, Bryenton was not an assailant. As a result of the incident, Acorn lost an eye, suffered skull fractures, and spent weeks in hospital.

But regardless of whether Bryenton actually punched Acorn, Douglas said when Bryenton showed up at the Euston Street boarding house demanding drugs from Acorn last November, he still had the intent to commit an illegal activity and had to have known a probable outcome would be violence.

It's on these grounds the judge found Bryenton guilty of assault causing bodily harm.

Bryenton will stay in custody until his sentencing, which is set for March 11.

The trial for the other man charged with aggravated assault in connection to the incident, 22-year-old Jeremy Joseph Cummiskey, is set to begin in provincial court on Tuesday.
