LAKEWOOD — Authorities say a hit-and-run crash that killed three people has closed all lanes of Interstate 5 southbound and three lanes northbound near Lakewood. The Washington State Patrol says a 23-year-old man was swerving across the southbound lanes when he struck a car at about 2:15 a.m. Thursday. That vehicle rolled over, killing three people inside, and its engine block launched into the northbound lanes, prompted another crash.
