20 March 1999,
The body of Joxelu Geresta Mugika Ttotto, a member of ETA, was found under an apple tree from a Errenteria farmhouse. A few days earlier he told a friend that he was being persecuted by the Spanish police, but that ETA could do nothing and denounce him if something happened to him. According to family and defense, he was arrested, drugged and dental microchip. This would explain why he lacked two tweezers and why he had another one cut.
