## Statement

DAG. Amy Sieminski failed to disclose Det. John Barnett's written notes until 1/4/2024, more than one year after I civilly sued her on 12/5/2022 for suborning perjury. This caused my criminal attorney unable to impeach John Barnett and Sgt. Jospeh Villalta-Moran about their contradictory testimony under oath during the 12/15/2023 testimonial hearing. Thankfully, Jospeh Villalta-Moran admitted the existence of the concealed notes during cross-examination, and Amy Sieminski ultimately produced the notes. With that notes, Honorable Mitzy Galis-Menendez found that Amy Sieminski violated Brady-Giglio rules, and finally granted my criminal attorney's motion to suppress evidence. Although Hon. Mitzy Galis-Menendez could not say that their conduct was willful or outrageous, but she agreed that their conduct was at very least due to palpable negligence. Given the fact I have civilly sued all three (Sieminski, Barnett, and Villalta-Moran), I can conclude their actions were intentionally against me as retaliations.
