The assault took place in international waters, a key part of cadet training.[AP News]

Merrone admitted to five charges, including aggravated sexual abuse and abusive sexual contact, just before his trial was to begin. Prosecutors detailed that Merrone lured cadets under false pretenses, drugged them with spiked alcohol, and then assaulted them. Digital evidence corroborated the victim’s lack of consent.[AP News]

Several other women accused Merrone of sexual assaults spanning three decades and were prepared to testify, bringing renewed scrutiny to the Merchant Marine Academy’s Sea Year program, which has faced multiple sexual abuse allegations previously. The program was suspended in 2016 and 2021 due to similar sexual misconduct concerns.[AP News]
