The Los Angeles Innocence Project
Analytic Investigations had the opportunity to meet Maurice Hastings at the California Association of Criminalists annual conference in 2024. Mr. Hastings spoke at the conference about his wrongful conviction of murder in 1988. He was ultimately exonerated in 2022, and found factually innocent in 2023, thanks to the assistance he received from the Los Angeles Innocence Project and their Director, Paula Mitchell.
Analytic Investigations spoke with Mr. Hastings and Ms. Mitchell after their presentation. Mr. Hastings thanked us for doing the work we do, stating that he knows there are other people “doing time” when they are innocent, and that he hopes experts will continue to provide services to help those who are wrongfully incarcerated.

-John Anthony Cole, initially charged with First Degree Premeditated Murder, subsequently reduced to Second Degree Homicide with the assistance of Analytic Investigations. For the full testimonial, click here.The approach taken by Analytic Investigations and Deborah Stonebarger has allowed my case to be viewed from a scientific standpoint that balanced the playing field with the interpretation and presentation of evidence attributed to my case as well as evidence that was not appropriately applied by investigators, crime lab personnel, medical examiners and the state’s prosecution. This is what “empowering our clients with knowledge” is all about….
[I am] forever grateful for their services.
