Lowe and colleagues refer to the violent breaking up and burying of carved stone monuments at Chiapa de Corzo, Chinkultic, and various sites in Guatemala and El Salvador. Gareth W. Lowe, Thomas A. Lee, Jr., and Eduardo Martinez E., Izapa: An Introduction to the Ruins and Monuments, NWAF 31 (1982), p. 28. At this same time at Chiapa de Corzo, the "Horcones occupation ended with its violent overthrow" accompanied by "an attitude of irreverence for both the dead and for certain conventions." Lowe, "Burial Customs," p. 73.
