Yabrán was born in Larroque, province of Entre Rios, in 1944, the seventh son of Nallib Miguel Yabrán and Emilia Tufic Marpez, both children of Lebanese immigrants. He moved to Buenos Aires in the early 60's, as he began to do business in the areas of security and banking transactions. In the 70's, he became one of the main shareholders of Ocasa, and at the end of President Raúl Alfonsín's term he began to operate airport security in Ezeiza. His name became known due to allegations of former economy minister Domingo Cavallo. At a session of the Congress in 1995, the then finance minister denounced Yabrán as a kind of mafia boss with political and judicial protection. Yabrán, currently known by the general public, was largely unknown at the time and the press did not have any pictures of him. Legally, Yabrán only declared a few companies, but Cavallo accused him of driving, through proxies, other major companies. Among them, Correo OCA, Ocasa, Ciccone Calcográfica and a transport and logistics company called Villalonga Furlong. These companies were sold to the Exxel Group for $605 million. The main accusation against Yabrán was that their transport and security companies were being used to hide drugs, weapons trafficking and money laundering. Among other things, he owned the private courier company OCASA, and the immense - of which are covered - EDCADASSA warehouses at the Ezeiza international airport in Buenos Aires. When his name became known due to allegations of former economy minister Domingo Cavallo, Yabrán was extremely secretive and jealous of his privacy. After the murder of photojournalist José Luis Cabezas, who had been investigating Yabrán, he was forced to come outin public and face the suspicions of society.
Close links with Menem's government
The killing of Cabezas embarrassed President Carlos Menem's government while Menem admitted that Emir Yoma was Alfredo Yabrán's friend, he denied that Yabran knew him. His former wife Zulema Yoma insisted that they were close friends, and was proven right when it was found out that Yabran had given Menem a mansion in Buenos Aires as a marriage gift. Justice Minister Elias Jassan had to resign over the 102 calls he personally made to Yabran and because of the calls that he had with Yabran's bodyguards the day after the murder of Cabezas. Cabinet MinisterJorge Rodriguez was criticized for receiving Yabran in the Casa Rosada.
Suicide
In 1998, Yabrán was found dead in one of his houses, with a gunshot through his face which left him nearly unrecognizable.
