From 02:02 -the tire tracks change significantly depending on the camera POV.
At 48:33- KJ spots the witness statement report but at 49:41-
when she picks it up it is a different sized paper with one
corner torn off.
Near the end, when KJ is viewing the crime scene, there is much more blood (appeared to be gallons) than could be drained from a single person under any circumstances, much less a person who survived the accident.
