The motorist who died after being felled by a knockout punch during a Brooklyn road-rage brawl earlier this month has been identified as a “brilliant” Long Island doctor and beloved married father of two.
Dr. Jaime Yun, 56, a cardiothoracic surgeon from Manhasset, died from a traumatic brain injury days after a man slugged him in the face and knocked him to the ground in Crown Heights on June 8.
“Words cannot describe how saddened I am to lose my dearest friend and brother,” former NYU classmate Sang Lee wrote in an online tribute book for Yun.
“Jaime was brilliant. He excelled in everything he did.”
Yun was born in Venezuela and later moved to Colombia with his family before migrating to the US in the 1970s, according to an obituary posted online.
He was a graduate of Columbia University and New York University Medical School, where he earned the nickname “99” from classmates — thanks to his tendency to routinely finish in the 99th percentile on his exams, according to his obit.

Police said Yun and 31-year-old Dexter Alexander got into a road-rage dispute at Schenectady Avenue and East New York Avenue shortly before 11:30 p.m. on June 8.

During the fight, Alexander allegedly punched Yun in the face, knocking to the ground and causing him to slam his head into the pavement, according to police.
The injured man was taken to Kings County Hospital, where he died on Friday.
His death was ruled a homicide by the city medical examiner’s office.

It was unclear if the assault charges against Alexander would be upgraded following Yun’s death.
He is survived by his wife, Tyan, his children, Christopher and Lauren, and five brothers.
“I will sorely miss Jaime’s friendship,” Lee, his former classmate, wrote in the online tribute. “Jaime was a genuine person who showed unwavering friendship. I will miss Jaime’s smile, sense of humor and love of gossip.”

A wake will be held Friday at the Fairchild Funeral Chapel in Manhasset, followed by a funeral service at the chapel at 8 p.m., his family said.
