Sean McKenna, 51, found to be high on heroin as he crashed into five vehicles on Jerusalem Avenue, leaving two injured in Seaford, NY

51-year-old Sean McKenna had herion in his vehicle and is believed to be under its influence when he struck five separate cars within a third of a mile while driving east on Jerusalem Avenue at about 5:49 p.m. He continued driving after each collision, until his car eventually left the roadway, struck a mailbox, destroyed about 100 feet of wooden fence, and finally crashed into a pole. Two people that he struck were injured, including a 28-year-old male who sustained serious injuries and was admitted to an intensive care unit, and a 24-year-old woman who had minor head injuries and has already been released from the hospital.
