Achaeologist Alejandro Tovalín Ahumada said: “Based on the results of these excavations, I think the murals refer to a change in the ruling lineage; this change was then achieved through battle, and the skeletal remains could possibly correspond to one of the most important captives of that battle, perhaps the head of the group that was overthrown by Chaan Muan II.”

“In other words: Chaan Muan II belonged to a distinct or secondary ruling lineage of Bonampak until the moment of the battle, towards the Late Classic period, and with the help of Yaxchilan, in a military and marital alliance - as he was married to a sister of Shield Jaguar III, ruler of the site mentioned – he was able to take the power over Bonampak.”
“Those portrayed in The Battle mural are not people of any important nearby settlement, but they might be the group that ruled Bonampak until then.” 

Another indication of this hypothesis, he said, is that all Mayan rulers of this period depicted the taking and killing of prisoners in stelae and lintels, marking their place of origin; in the murals of Bonampak no such data is found, but there are indications that they relate to an important group. Finally, Tovalín stated that the archaeological pieces have been transferred to the INAH Center in Chiapas for cleaning and restoration, while the crypt has already been sealed. In the same manner, the bones remain under analysis by the physical anthropologist Montes, who has determined the presence of a strong osteoarthritis. They have also collected a charcoal sample associated with the crypt, which will be send to the Radiocarbon Dating Laboratory of the INAH to be dated. "With these and other DNA studies, together with the comparing of 30 skeletons that were previously found on the site, we will be able to determine the origin of the individual and a get more precise date of his burial," he added. In regards to the conservation of the murals of Bonampak, Lilia Rivero Weber, head of the CNCPC, specified that this project began in 2009 with the purpose of maintaining these artistic works which had passed over 10 years without receiving deep treatment. The restorer explained that interventions from different disciplines took place years ago, but that this is the first time for an interdisciplinary group to be simultaneously involved in understanding the mechanisms of deterioration of the building, caused by the earthquakes of 2005, 2006 and 2007. "The intervention project contemplated a complete study of the architecture of the Temple of the Paintings, and once we get the diagnosis, we will determine how to treat the cavities," concluded Rivero.
