A doctor and father of two has been identified as the victim of a road-rage incident in Brooklyn, New York, on June 8, as dense smog from Canadian wildfires obscured much of the city. 

Dexter Alexander, 31, has been charged with assault after he and victim Jaime Yun, 56, of Manhasset, got into a "physical altercation" that morning near Crown Heights following an apparent road-rage incident, according to police.

Alexander allegedly struck Yun in the head and left him lying on the ground, the New York Police Department (NYPD) said.

When police arrived, Yun was "in stable condition with a head injury" but got worse as time elapsed, and he was transported to a nearby hospital.

Yun grew up in Venezuela and moved to Colombia with his parents and five brothers, who all eventually immigrated to New York City in the 1970s.
