The salvage excavation of a looters' tunnel in Structure 44, a poorly constructed 8th-century temple, revealed that the loose rubble infill of the temple had collapsed the tunnel before it reached a royal tomb, which was left intact. The tomb was excavated by Juan Antonio Valdés and was discovered to be that of king Chanal Balam, the ruler who overthrew Dos Pilas in AD 761. The funerary temple containing the tomb possesses inscriptions celebrating Chanal Balam's great victory over his former overlord.
