Jason Newlin
Leon County State Attorney's Office investigator who testified in the Garcia–Magbanua 2019 trial, the 2022 Magbanua retrial, and the Donna Adelson 2025 trial.
About
Newlin's testimony connects the Rivera cooperation timeline with the later documentary presentation of the Adelson family's divorce litigation. The earlier two trials preserve his account of unrecorded meetings, discovery and media exposure, firearm follow-up, and other investigative limits. The Donna Adelson trial separately records how the State assembled and authenticated the filing-and-email exhibit used to present the family-law history.
