Episode #1.7 - S1-E7
Factual error: The victim has been shot while he was lying in the coffin with his arms crossed. Somehow, he keeps his arms perfectly crossed even when he's dead, despite being carried around in a casket propped in vertical position merely a little more than 15 minutes later. Rigor mortis takes way longer to begin, his lifeless arms would have flailed off position a long time before, not stayed in the dramatic mummy position with no supports to hold them in place.

Factual error: When the tracking dog finds a gun in some bushes, Kenda, who is narrating, says that the gun was a Ruger Mark I, which is a semiautomatic target pistol; but the gun shown in the reenactment is a snub-nose .38 Special revolver.
