Something else that I find suspicious is that the only two eye-witnesses, of Justin's departure and return (neighbor Lyle + Girlfriend/Wife) are very close to the government.
Lyle's LinkedIn account says: "Customer Advisor, Public Sector - Government"
And Stephanie had a run-in with the law after ramming a cop car, summer of 2015, while under the influence.
Lyle and Stephanie follow each other on twitter.
