'Golden Boy' Ivy League Grad Who Killed Hedge-Fund Dad Over Allowance Breaks Silence in Prison Interview
Thomas Gilbert Jr., the Princeton University graduate once known as Manhattan’s “golden boy,” has broken his public silence nearly 10 years after fatally shooting his hedge-fund manager father inside the family’s luxury Beekman Place apartment. In a rare prison interview aired by Court TV, Gilbert—now 40 and incarcerated at Clinton Correctional Facility in upstate New York—appeared gaunt and withdrawn, occasionally mumbling responses before abruptly ending the conversation.
“I just want to present my case,” Gilbert told the network. “That narrative misses a lot of the facts of the case, particularly pertaining to my innocence.”
The 2015 killing sent shockwaves through elite Manhattan circles. Thomas Gilbert Sr., 70, founder of Wainscott Capital Partners Fund, was shot in the head at close range after a dispute over his son’s weekly allowance—which had been reduced to $1,000. Prosecutors said the younger Gilbert sent his mother on a bizarre errand to buy a Coca-Cola, then pulled the trigger and placed the Glock pistol in his father’s hand to stage a suicide.
Shelley Gilbert, the victim’s wife, identified her son as the killer moments after the shooting. In a 911 call played during the Court TV special, she said, “My son—he was nuts. But I didn’t know he was this nuts.”
The interview has reignited debate about mental health and criminal responsibility. Over the years, doctors diagnosed Gilbert with schizophrenia, bipolar disorder and obsessive-compulsive disorder. Forensic psychologist Dr. N.G. Berrill, who appeared in the special, noted that mental illness does not automatically negate legal culpability. “He’s mentally ill, but still criminally responsible,” Berrill said.
Gilbert’s defense team argued insanity at trial, but a Manhattan jury rejected the claim in 2019. Justice Melissa Jackson, who sentenced him to 30 years to life, stated, “You knew exactly what you were doing. You were not insane at the time you killed your father. You were not insane then. You are not insane now.”
Prosecutors presented evidence that Gilbert purchased the .40-caliber Glock months earlier from an Ohio seller, then meticulously attempted to mask the murder as a suicide. At sentencing, then-Manhattan District Attorney Cyrus Vance called the crime “cold-blooded” and said the defendant had finally been held accountable.
The case has drawn comparisons to other high-profile family killings involving wealth, privilege and mental health struggles. Experts point to the tragedy as a cautionary tale about the pressures faced by children of ultra-wealthy families, and the difficulty of recognizing when a loved one’s instability turns dangerous. True-crime author John Glatt, who wrote the book Golden Boy about the case, detailed Gilbert’s growing paranoia in the years before the murder, noting that friends watched the once-promising Ivy League graduate unravel.
Shelley Gilbert, in a plea at sentencing, asked the judge to send her son to a psychiatric facility rather than prison. “I know this is what my husband would have wanted for him,” she said. The court instead ordered prison time, and Gilbert remains at Clinton Correctional Facility, eligible for parole after serving three decades.
