The agent of this attack is clearly from the Kan ("Snake") polity (later based in Calakmul but probably centered elsewhere at this time, possibly in Dzibanche). The last collocation of D1 shows the snake head of that kingdom's emblem glyph, with the ka prefix indicating that it is to be pronounced Kan instead of Chan. To the left of the emblem glyph at the bottom of D1 is a name which Simon Martin, in his first attendance at the Texas Maya Meetings, identified as that of a known king of Kan.

Note: It has been suggested that the emblem glyph of Snake was pronounced Kan instead of Chan because the inhabitants or rulers of the early Snake kingdom spoke Yukatekan, but Stanley Guenter (personal communication, 2003) finds it more probable that the Kan pronunciation reflects the parent proto-Mayan language. He sees the early Snake Kingdom as being proto-Ch'olan/Tzeltalan rather than Yukatekan in its language affiliation and asserts that archaeology can be used to support this epigraphic argument.
