CLASS REUNION

Three decades had passed since their 1987 graduation from the Polytechnic School of Rosario, Argentina. But the Argentine victims of Tuesday’s truck attack, most of them architects, had remained close friends, getting together several times a year.

The five dead were among a group of 10 friends marking their graduation by touring New York and Boston, where at least one survivor of the group lived.

One victim, Hernan Diego Mendoza, was an architect and father of three who designed the home of his close friend, Estanislao Beas.

“The news destroyed my wife and I,” Beas said. “We had a tight bond. We cared for him so much. It’s incredible that this happened to him and that he was there at that time.”

The Argentine foreign ministry identified the other victims as Ariel Erlij, Diego Enrique Angelini, Alejandro Damian Pagnucco and Hernan Ferruchi.

The reunion trip was paid for by Erlij, the chief executive of Ivanar, an Argentine steel products manufacturing company, according to Argentina’s La Nacion newspaper.

President Mauricio Macri said Wednesday in Buenos Aires that the attack “hit all Argentines hard.”
