 Monument 4 appears to be a sculpture of a captive, leaning slightly forward and with the hands tied behind its back. It was found on the lands of the San Isidro plantation but it is not known exactly where. It was moved to the Museo Nacional de Arqueología y Etnología in Guatemala City. This monument probably dates to the Late Preclassic. It is 0.87 metres (34 in) high and about 0.4 metres (16 in) wide.
