Cold Case Cops Try To Solve A Nearly Decade-Old Mystery

The irony is that prosecutors may not have had enough to convict Perry

At the age of 45, Perry March will most likely spend the rest of his natural life in prison. Convicted both of conspiracy to commit murder and second degree murder, the judge sentenced Perry March to 56 years.

"I'm sorry and sad that our grandchildren have had to live ten years without their mother and with the person who took her from them," Janet's mother Carolyn commented after the sentencing.

Sammy, now age 16 and Tzipi, age 13, are living with their grandparents Carolyn and Larry Levine in Nashville.

As for Arthur March. the man who helped convict his own son, the judge rejected his plea agreement of 18 months, and sentences him to five years.

And two Nashville detectives were happy to finally close the book on Perry March.

"His days are done in terms of Perry March, Perry March, Perry March. That's over. And now maybe the attention will be on Janet versus on Perry. It was a satisfaction of knowing that finally some justice for Janet so to speak, she's finally gonna get some justice," Det. Postiglione says.

"There's not a day that goes by that I don't think about my daughter," Carolyn comments. "She had so many talents. She was a very caring, compassionate person. Every parent thinks their kid is special. But she really was."

Arthur March died of natural causes in federal prison on December 21, 2006. He was 78 years old.

Perry March will be eligible for parole in 30 years. He'll be 75.

A court has given the Levine's permanent custody of the children.
