Continuity mistake: When the cop is talking to the gas station security manager the security man has his badge on the right of his shirt. The following camera shot shows it on his left and then swaps back again when they go to look at the security cameras. (01:01:00)
Revealing mistake: The "bridge" within the crime scene tape is obviously a prop. It should be a continuation of the road, but it is tilted to the left and is more vertical (around 45°). The bridge isn't even very high. When Byron and others go under the bridge to look at the dead girl, there is only a few feet above their heads (clearance under the bridge). (00:04:54)
