The offenders were sentenced for their roles in the unprovoked shooting death of a random victim during an attempted robbery.
McDonald, convicted of second-degree murder, was sentenced to life imprisonment with 25 years of parole ineligibility, to be served consecutively to a previous life sentence for another murder.
Lako, convicted of manslaughter, was sentenced to 12 years' imprisonment.
The court denied Lako's request for enhanced pre-sentence custody credit related to the COVID-19 pandemic, finding insufficient evidence of unique personal vulnerability or measurable impact beyond that experienced by the general public.
