Chris says each time he talked to police, he gave them his alibi.

He had not seen Tara in days.

The night before the murder, he slept over at his parents' house, almost an hour from the crime scene.

That morning, he went to work, stopping at a few places along the way.

It happened again and again.

The phone would ring, and the questions would start.

Did anyone ever come out and just tell you that you were a suspect?

Chris says it was excruciating because all he ever wanted to do was spend the rest of his life with Tara.

He says he knew she was special just a few weeks after their first date.

They ran into each other at a crowded college bar.
