On the night of June 28, 1993, Eileen Sarmenta and Allan Gomez, students of the University of the Philippines, Los Baños (UPLB), were abducted at gunpoint by men working for Antonio Sanchez, the mayor of Calauan, Laguna. The students were brought to Sanchez's farm in Barangay Curba, where both were bound and gagged. Court records showed Sanchez's men also brought Gomez along "to avoid complications". The students were brought inside a resthouse, where Sarmenta was taken into Sanchez's room while Gomez was beaten by Luis Corcolon, Rogelio "Boy" Corcolon, Zoilo Ama and George Medialdea and thereafter thrown out of the resthouse.
