The man, whose name cannot be released, was just 17 when he picked Szendrei at random and killed her in a Delta park by beating her with a metal pipe.
He was initially charged with first-degree murder but pleaded guilty to second-degree murder last year.
A judge must now decide whether he will be sentenced as an adult or as a teenager.
Today, SFU forensic psychologist Robert Ley is on the stand and is expected to say the man should be spending time in a youth institute.
If sentenced as a youth, the offender will have to serve seven years, with a maximum of four years in prison and the remainder to be served in the community.
If sentenced as an adult, he'll receive an automatic life sentence with parole eligibility to be determined by a judge. If sentenced as an adult, his name will also become public.
Earlier this week, psychiatrists told the court the offender should be sentenced as an adult so he could be supervised by the parole boards.
