BUENOS AIRES, July 13 (UPI) -- Families of the 44 sailors who died in the sinking of Argentina's ARA San Juan submarine said they will appeal the verdict that found former Navy Capt. Claudio Villamide guilty nearly nine years after the November 2017 tragedy.

The plaintiffs also said they will seek to have the trial annulled, arguing that investigators never exhausted the scientific evidence needed to reconstruct what happened during the submarine's mission in the South Atlantic.

"We completely disagree with the ruling," Luis Tagliapietra, an attorney representing 12 families and the father of Alejandro Tagliapietra, one of the sailors who died, told UPI. He said the verdict was the result of an incomplete investigation.

"Not because these people bear no responsibility, but because of how the entire process unfolded," he said.
