Thiago Nahuel Pocovi, 26, is accused of manslaughter over the death of Sofía Devries. The charge comes five months after Devries, 23, disappeared beneath the surface while completing an advanced diving course in Argentina in February.
The tragedy, which should have been a routine scuba certification dive, occurred in one of the country's most famous diving destinations, Puerto Madryn. According to prosecutors, Pocovi allegedly failed to follow established safety protocols during the excursion, which prompted the criminal investigation that could lead to a full trial.
