Investigator Mike Mayhew

The gas station was near Tarr's home, an hour from the crime scene. Andrew Affronti is the Montgomery County state's attorney. He has dystonia, a condition that causes muscle tics and tremors. So why is it significant? So he went out and got some gas.

Investigators believed it was proof Tar was lying about his whereabouts that night. They placed him under arrest. A frontie says they arrested Tar immediately because they feared Chris's life was in danger and they hadn't found the murder weapon.

You told the police you had no idea where Farmersville is. That was a lie. You lied about getting gas in your car that night. When he spoke with us, Tar admitted he was at Chris Smith's house the night before Thanksgiving, placing himself at the scene of the crime.

Just a few weeks earlier, Amy says Leslie told her that Tar had shown up while she was on a first date with a different guy.
