A 67-year-old grandmother is dead, and an 8-year-old boy is in critical condition after a driver went on a reckless rampage in Bed Stuy, police say.

According to authorities, the suspected driver was trying to get away from police at the time of the incident. Officers say it all started after they noticed the driver's car had mismatched plates.

At around 7 p.m. Saturday, an officer noticed the car's plates and two men in the vehicle allegedly smoking marijuana. The officers attempted to stop the vehicle at Ralph Avenue and Chauncey Street, but it sped off at high speed.
