A nationally renowned oncologist watched in anguish as his 9-year-old son was fatally hit by a cab just steps from their Upper West Side apartment Friday night.
The dad and boy were crossing the street at West End Avenue and 97th Street shortly before 9 p.m. — about a half hour after a 73-year-old man was killed in a separate accident two blocks away.
That man was struck and dragged by a private tour bus on Broadway and West 96th Street.
A doorman heard the dad, Dr. Richard Stock, 51, cry out in horror after the cab hit young Cooper as it made a left turn onto West End Avenue.
“It was a terrifying scream,” said Alex Lassi, the doorman.
Richard, who suffered a leg injury, and his son were taken to St. Luke’s Hospital, where Cooper was pronounced dead.
Richard is a radiation oncologist who treated former Mayor Rudy Giuliani for prostate cancer in 2000. He teaches at Mt. Sinai School of Medicine and lectures across the world on his specializations including prostate and bladder cancer.
Lassi said Richard was hysterical, “trying to hold onto his child” and wailing “Oh, my God! No, no, no!”
His wife, Dana Stock, was alerted to the crash by her doorman and rushed down from the family’s West End Avenue apartment at 771 West End Ave.
Dana sprinted down the street to find her son bloodied on the pavement, another doorman said.
Two passengers in a passing vehicle stopped to help the child, witnesses said.
Lassi said one of the Good Samaritans called 911 and reported that the boy was still breathing.
But by the time paramedics arrived, Cooper “looked lifeless” and “had blood all over his face,” a neighbor said.
“I saw him when they brought him in,” an emergency-room patient named Monique said.
“He was covered in a white sheet — the whole sheet was bloody,” she said.
Cooper “was a super, super kid, a special kid,” one family friend said, calling the boy “exceptionally bright and a wizard with numbers.”
Cooper has an older sister, the family’s doorman said.
He added that the father and son often attended Knick games.
In the earlier incident, the unidentified elderly man died at the scene after he was pulled along the pavement by a green charter bus heading south on Broadway and turning east onto 96th Street.
That driver also stayed at the scene of the accident.
Neither the bus driver nor the cab driver was charged Friday, but the investigations are continuing.
