William Duplessie, a 32-year-old resident of Miami, surrendered to authorities and faces charges in the NYC crypto kidnapping case.
Duplessie's arrest follows those of alleged accomplices John Woeltz and Beatrice Folchi, with Woeltz remaining in custody for further investigation.
The victim, an Italian national held captive for nearly three weeks, escaped and reported being beaten and tortured to access his cryptocurrency accounts.
The case highlights the risks faced by high-profile crypto holders, and authorities continue to investigate the conspiracy with potential for more arrests.
