What happened: Florida officials have released an investigative report detailing the May passing of Claude Lemieux. The former NHL forward was discovered deceased by his son Brendan at a family-owned showroom in Lake Park. His death was officially ruled a suicide.

Why it matters: Lemieux had maintained his sobriety for 12 years before the relapse that preceded his death at age 60. His family subsequently donated his brain to scientific research to help advance the study of Chronic Traumatic Encephalopathy.

What to watch: Researchers will examine Lemieux's brain for signs of trauma as the hockey community remembers his 21-season career.
