BUENOS AIRES, Argentina (AP) — Four former Argentine navy officers are on trial for the 2017 sinking of the ARA San Juan, which killed 44 crew members. Prosecutors say the officers neglected duties and ignored serious maintenance problems. On Tuesday, a court in Santa Cruz opened the case. The submarine vanished on Nov. 15, 2017, during a trip after a training exercise. The crew reported water entering batteries, then lost contact. Investigators say water reached a battery tank and triggered a short circuit and fire. The submarine then plunged and imploded at extreme depth. Relatives of the deceased crew members argue that the current trial falls short of achieving true justice.
