A man was killed and a 12-year-old was seriously injured in separate incidents involving hit-and-run drivers in Brooklyn and the Bronx.

Police say that 49-year-old Ian Paul Bubb was crossing Glenwood Road, from south to north, outside the marked crosswalk at Rockaway Parkway when he was struck by 26-year-old driver Richard Williams around 8:20 p.m. on Friday. Bubb was transported to Brookdale Hospital, where he was pronounced deceased. Williams, who continued traveling eastbound on Glenwood Road, was arrested afterwards, and charged with leaving the scene of an accident resulting in death.

In the other incident, a 12-year-old boy was running on the street just after 5 p.m. on May 16th when he was struck by a driver in a gray Mazda CX-9, who was traveling southbound on Logan Avenue toward Dewey Avenue in The Bronx. Cops say the driver initially stopped and checked on the victim, but then left the scene without reporting the incident. You can see surveillance video of the vehicle below.
