Justice John Fregeau has reserved his decision on a conflict of interest application in the case against the accused killer of Renée Sweeney, a year after the man's arrest.
A publication ban means details of the application cannot be reported.
Wright appeared in person for the three-hour hearing, dressed in a blue dress shirt and black pants. His head was shaved, but he is sporting a large, bushy beard.
Wright is charged with second degree murder in the 1998 slaying of Sweeney.
Police say at the time of the offence, Wright lived in Sudbury and was an 18-year-old student at Lockerby Composite School.
Wright was arrested Dec. 11, 2018 at the North Bay Regional Health Centre. He was working as a laboratory technician.
In August, the Crown Attorney's office succeeded in securing a direct indictment, meaning there will be no preliminary hearing, and the case will go directly to trial.
A date for trial has not yet been set.
