NASHVILLE, Tenn. -- So what does Arthur March really think about his convicted killer son?

What does he think about the judge's decision to renege on a plea deal in return for the testimony that helped put away Perry March?

His once happy-go-lucky attitude was left in Mexico.

If you were the elder March, how would you feel about your son, Perry, who got you in serious trouble, who got you kicked out of Mexico, jailed here for months, and now imprisoned in a Texas federal facility?

"Arthur doesn't make it a habit to sit around and cry over spilled milk, blame his son. Arthur loves his children, unconditionally," said Fletcher Long, Arthur March's attorney.

For the 10 years since Janet March, Perry's wife, disappeared, Arthur felt in his own mind that his son had murdered her, Long says Arthur told him.

But Perry's father had told people so many times that his son was innocent that he literally diluted his memory into believing it was true, although knowing in his mind that Perry had murdered Janet.

"He loved his children and he may be willing to go too far for his children. Arthur thought of Perry as kind of a near-do-well, naive, unsophisticated, unsavory individual that he always had to come behind him to clean up," said Long.

So, what did Arthur March say when Federal Judge Todd Campbell threw out a government-agreed 18-months plea-bargain agreement and jumped it to five year sentence?

"What did he say, honestly to me. Well, he leaned over and said I got 'F'd.' To which I responded, 'You certainly did,' " said Long.

Before the 78-year-old Arthur was transferred to the Federal Detention Center here at Fort Worth, Texas, Long said he had lost hope.

"Arthur, I don't believe has anything for which to live. I think he has taken from him any reasonable expectation he'll ever breath free air again," said Long.

Channel 4’s Larry Brinton interviewed Arthur March on a number of occasions in Chicago and Mexico. He said the down-trodden man the public has seen on television is not the smiling face who walked the streets of Ajijic, Mexico, laughing and shouting to friends.
