The fatal crash occurred at 12:27 a.m. on Sept. 19 in on Round Swamp Round in Old Bethpage. Police said the victim, 42-year-old Robert Michaels, had been walking his dog south on Round Swamp Road when a 2013 Dodge Avenger hit him.
The car’s driver, Matthew Johnstone, 37, of 185 Pine St., North Massapequa, allegedly fled the scene without stopping.
After police responded, Michaels was transported to Nassau University Medical Center in East Meadow, where he was pronounced dead by hospital staff. Police said the victim’s dog died at the scene.
Cops arrested Johnstone after he returned to the scene. He was booked on a charge of leaving the scene of an incident without reporting and will be arraigned Thursday at First District Court in Hempstead.
