On this page you will find a list of some of our more interesting investigations. While OKPRI has conducted countless numbers of investigations in the past 19 years, we have only listed those cases that have yielded a lot of recorded evidence. We began our journey in 2000 but we did not publish any of our investigations until 2002. As cases are completed, they will be added to this page. Not all links will work at this time but as pages/cases are added, they will be made available for viewing. Thank you for your patience as our website is continuously updated.
