On May 20 every year, Malik’s wife, Lisa Sealy, marks the solemn occasion by “remembering to breathe.” Ann simply tries to get through the day. Amir Sealy celebrates his brother by thinking of the good times they had. Twenty years ago Wednesday, Sealy was driving home from Kevin Garnett’s 24th birthday in St. Louis Park, Minn., when his car was hit by a pickup truck going the wrong way on a divided highway. Souksangouane Phengsene, the truck’s driver, was intoxicated and served four years in prison. By the early morning hours, the Timberwolves had found out the grim news: Sealy was gone.
