Guillermo Roberto Beausire Alonso

Guillermo Roberto Beausire Alonso (born 3 December 1948 – disappeared 2 July 1975), anglicised as William Beausire, was a British-Chilean commercial engineer who was abducted by DINA agents at Ministro Pistarini International Airport, Buenos Aires on 2 November 1974. Returned to Chile, Beausire was held in various DINA torture and detention centres before his enforced disappearance on 2 July 1975. Beausire father, Wilfrid Richard Beausire Pascal, was English and his Mother, Rosa Herminia Inés Alonso Boudat, was Chilean. The Beasuire family lived in the upper class Santiago communes of Las Condes and Providencia.

In December 1973, Beausire graduated with a degree in Commercial Engineering from the then Valparaíso Business School (Now Adolfo Ibáñez University).

Upon Beausire's arrival at Buenos Aires Ministro Pistarini International Airport Beasire was called over to the ″International Police Control″ desk. Witnesses say that Beausire was given electric shocks, had sticks forced into his rectum and was hung in the air.

Disappearance On 17 May 1975 he was taken to another DINA centre in Irán Street, Santiago. The last anyone heard of William Beausire was on 2 July of that year, when witnesses reported seeing DINA officers taking him from a building in Irán Street, Santiago.

Aftermath and international response In June 1976, the UK Government referred the case to the United Nations.

In 1993, Tristan Garel-Jones MP presented the findings of the Chilean National Commission for Truth and Reconciliation Report to the House of Commons. The report concluded that Beausire had been arrested in Buenos Aires on the 2 November 1974, before being handed over to DINA custody, where he remained until his enforced disappearance.
