Finally just watched. There's only 1 plot hole
So I know this is a pretty dead forum but I finally just finished watching this movie. Unsurprisingly there are multiple "Plot hole" threads but nobody mentioned what I thought was the most glaring one.
Keller's truck would have been parked somewhere on the property in back of the house. Holly Jones is seen parking moments before Loki arives. Also once police arrive on the scene after Loki calls it in, Kellers tools and gun (which I'll assume was registered since he wasn't a criminal) would have been found in a search of the property. The car and the physical evidence inside would have prompted a thorough search.
They might not have found him that night but they certainly would have before forensics started systematicly excavating the property.
Great movie and I loved the ending.
