Coinbase’s Paul Grewal Tells Story of Nightclub Crime Spree That Led to Multiple Convictions

Crypto exchange Coinbase’s blockchain forensics team played a critical role in a New York City criminal investigation that led to multiple convictions, according to the exchange’s chief legal officer.

Paul Grewal spoke about the case on Tuesday as part of Coinbase’s ongoing “Consumer Protection Tuesday” initiative. The case centered on a pattern of attacks where suspects targeted individuals—often from the LGBTQ+ community—outside bars and clubs in Manhattan’s 7th and 9th Precincts.

Victims were drugged, their phones stolen, and financial and crypto accounts emptied using face ID or forced PIN entry. In some instances, victims were found dead from fentanyl-laced substances. In total, over $250,000 was stolen across multiple platforms, including Coinbase.

The criminal group quickly transferred funds through banking apps, peer-to-peer services, and crypto platforms. Tragically, several victims never recovered.

Coinbase’s rapid response and blockchain analysis proved instrumental in tracking the movement of stolen funds.

“Our blockchain analysis tied multiple wallets to the same crew, helped recover evidence across fiat and crypto rails, and supported convictions on 24 counts, including second-degree murder. The case shows crypto isn’t the risk—it’s the trail of proof that put violent criminals behind bars,” Grewal said.

The data supported the prosecution of Jayqwan Hamilton, Robert DeMaio, and Jacob Barroso, who were found guilty on 24 charges, including murder, robbery, and conspiracy. Two also faced burglary convictions.

“It was one of the most difficult cases we’ve supported. But it’s also one that shows the enduring power of blockchain to uncover truth, even when suspects go to great lengths to hide their tracks,” Grewal added.

He also noted the often-negative perception of crypto in law enforcement contexts.

“This case was a reminder that crypto doesn’t exist in a vacuum. It intersects with the real world—in this case, a deeply tragic one. Our job at Coinbase is to ensure it’s part of the solution.”
