John Castic, a 27-year-old Goldman Sachs analyst found dead in Newtown Creek this week after attending a concert at Brooklyn Mirage, died by drowning, his father confirmed to The Post.
In a Thursday phone interview, Jeffrey Castic said his son’s “official cause of death is drowning.”
The revelation comes a day after the elder Castic told The Daily Mail his son may have suffered a deadly allergic reaction after consuming peanut products.
“We think he either had an allergic reaction — he was allergic to peanuts and maybe ate something without realizing that it contained peanuts — or there was an undetected allergy mixed with alcohol,” the elder Castic told the Daily Mail on Wednesday.
But a day later, the heartbroken dad said the family “had very low information” when he suggested the peanut butter allergy was a factor, and that “we weren’t sure at the time.”
In the Daily Mail interview, Jeffrey Castic said his son had told his friends he wasn’t feeling well before deciding to leave by himself.
“He was at the club and he started to catch ill so he said to his friends that he was going home,” he said.
John Castic – described by his dad as a “bright, charismatic young man” who “had lots of friends and loved to travel” – was captured on surveillance video walking calmly along Stewart Avenue from the venue, not far from where his body was recovered in Newtown Creek on Tuesday.
By Friday afternoon, the city medical examiner’s office had not officially released a ruling on the young man’s death.
“The final determination is pending results of toxicology testing,” a spokeswoman said.
“I am not able to comment on conversations between our doctors and families.”
The family has said it’s been given no indication that foul play was involved in John’s death.
“Right now we’re just focusing on the fact that in 27 years, he has impacted a lot of people,” his father said.
“We’re just trying to honor his life. We’re trying to move past all of that now – you know, it’s not easy.”
Jeffrey Castic said the family has been coping with the support of John’s friends.
“I have to admit his friends have been amazing,” he said.
“They’ve been incredibly supportive and caring.”
The young analyst’s body was recovered after a man noticed a bloated, shirtless body floating in the English Kills, a branch of the East River tributary, near 1100 Grand St.
Police sources have said there were no obvious signs of trauma, apart from drowning.

John Castic was the second young man to have disappeared near the Brooklyn Mirage and was later found dead in the same creek.
Karl Clemente, also 27, was turned away from the venue on June 11 — and found dead in Newtown Creek a few days later, sources have said.
Sources have said Clemente’s death did not appear to be suspicious.
Meanwhile, Karl’s dad, Alexander Clemente, told The Post this week there’s “so much similarity” between his son’s case and that of Castic — and wondered why it took another young man to turn up dead in the creek before the world took notice.
“When you lose one person in such circumstances, it’s too much,” Clemente, 65, said Wednesday.
“If you lose a second person, it’s unbearable. Why did we wait?”
Police sources have said authorities don’t think the two cases are related.
Instead, police are treating them like an unfortunate coincidence, the sources added.
