I appreciate that the police have reviewed the connection but you need to put yourself in the position of a serial killer. No one knows at that point he is a serial killer, to make sure he has an alibi first have a hospital appointment, secondly get yourself on CCTV in your home town, drive someone else's car, leave your phone at home, pay cash wherever you go. Easily done if you have multiple cars at your disposal and friends you can borrow a car off.
As for police, unfortunately, because of personal experience, they dismiss the most obvious things. I would like to have confidence in the police but unfortunately I don't.
