Why Elic Didn't Drive Past the Kennels on His Way Out of the Estate

Elic chose not to drive past the dog kennels on his way out of the estate. He would have been able to see if they were down there. And although Elic was wearing totally clean clothes, when the police showed up, there was gunshot residue on his car seatbelt. Maggie's blood was found on the steering wheel. This is the thing. Sometimes the absence of evidence looks really, really suspicious. Like when your own wife's DNA is not anywhere on you.
