Without Evidence

[1] It stars Scott Plank, Anna Gunn, Angelina Jolie, Paul Perri, and Andrew Prine.

Without Evidence is based on the true story of Michael Francke, who was the Head of Corrections for the state of Oregon before being murdered.

Just before his murder, Francke visits his brother and informs him he's been "stepping on some toes, found some things and got to clean house."

When Michael is killed, his brother begins his own investigation into the murder, leading him to more lies and deceit.

The "things" that Franke found could have been what an inmate-Douglas Bennett revealed later in several lawsuits about the illegal food used in prison.
