NEW YORK CITY, NEW YORK: John Castic, a 27-year-old analyst at Goldman Sachs, who was reported missing after attending a concert at The Brooklyn Mirage, was discovered dead in Newtown Creek on Tuesday, August 1. His father, Jeffrey Castic, has now confirmed that the cause of his son's death was drowning, as per The New York Post.

During a phone interview on August 3, Jeffrey Castic revealed that the official determination of his son's cause of death is attributed to drowning. This disclosure comes in the wake of his statements to The Daily Mail a day prior, in which he had speculated that his son might have experienced a fatal allergic reaction due to the consumption of peanut products.

Did John Castic die of peanut butter allergy?

On August 2, the father had said, "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," to the Daily Mail. However, a day later, the grieving father clarified that the family had been operating with limited information when he initially suggested the peanut butter allergy might have been a contributing factor. In an interview with the Daily Mail, Jeffrey conveyed that, at that moment, they were uncertain about the circumstances. He even revealed that his son had informed his friends of not feeling well and subsequently made the decision to leave the club by himself to go home.

'We’re just trying to honor his life'

Describing John as a "bright, charismatic young man" who was sociable and had a penchant for travel, Jeffrey stated that his son was captured on surveillance footage calmly walking along Stewart Avenue from the venue. The location of this footage was in close proximity to where John's body was eventually discovered in Newtown Creek on August 1.

There has been no update about John's official cause of death from the city's medical examiner's office. However, a spokeswoman noted that the final determination was pending the outcome of toxicology testing and refrained from commenting on interactions between their medical professionals and the families involved. The family has emphasized that there has been no indication suggesting the involvement of foul play in John's death. "Right now we’re just focusing on the fact that in 27 years, he has impacted a lot of people. 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 stated.
