A week after the Ampatuan Massacre of Nov. 23, 2009, the Ampatuans tried to secure amnesty for dozens of their high-powered, high-end firearms. After the massacre, the AFP unearthed or seized 1,200 illegal firearms in Maguindanao, including at least 300 reportedly linked to the incident.

Three years after the Ampatuan Massacre trial began, the high court in December 2013 assigned an "assisting judge" to speed up the process.

From 2002 to 2008, COA reports had scored huge expenses for what could have been identical projects in Maguindanao and ARMM, under the Ampatuans. The reports painted a sorry picture of how one powerful clan could have dipped into public coffers, willfully and wantonly, as if these were its personal purse.

Numerous motions filed by lawyers of the accused Ampatuans had stretched the pace of the trial interminably. By 2013, they had filed nine motions for the judge to recuse herself. Bail hearings for 70 detained suspects and lead accused, Datu Unsay Ampatuan, ended only in 2017.
