How Did Nathan's Guns Add Up?

The more we start looking at the house, it just didn't seem like a real burglary. There was a junk drawer that was perfectly lain on the floor. Why would a burglar even go through a junk drawer with pins? The fact that he happened to own the same type of gun used in danice's murder did not add up for police. They also ana things nathan had told them during his interview at the police station the night of the murder. i think he was trying to alude to the fact that the burglar must have got mutnto it and taken it. Yes.
