Do all the statements corroborate each other?
Are there ANY discrepancies?

Were they paid to stop the transport and let someone in to settle a score?
Is there anything in their record showing a pattern?
Are there any prior complaints against the officers involved?
Were the 2 detainees really separated?
Why don't you know the status of the other detainee?
If one detainee was injured to the point of being deceased, is the other detainee harmed at all?
Justice rushed is justice perverted.
Charging someone with a crime while the investigation counties is commonplace. Especially if they were the only ones at the murder scene, that weren't in handcuffs.
