The producers should have given him a lie detector test. He looks like someone who is not cunning enough to beat a lie detector test.
How did his hair get into the lace? The documentary failed to explain that contradiction where he can be used to bust the alibi and at the same time, he is there at the murder scene with a trace of his DNA in the lace.
It's too bad the cops are unethical in that area, otherwise, they would pursue this area and see who is lying and who is not. If Hobbs possibly abused his daughter, why wouldn't he be capable of this murder?
