A Fairfield mother was jailed for a third day Thursday after refusing to reveal the whereabouts of her 14-year-old son.

Before a Bridgeport Superior courtroom packed with news media and spectators, Kathyrn Sorrentino, her hands secured behind her back, continued to maintain she has no information on the location of Storm Sorrentino, the subject of a nationwide search.

She also told state Superior Court Judge Gerard Adelman she would be willing to take a lie detector test.

"It is the court's observation of Miss Sorrentino that, except for a few tears yesterday, she has exhibited little or no concern that her son has been missing for over 30 days," the judge said. "It's difficult for the court to accept the fact that a mother whose son has been missing that long would not exhibit emotion and be distraught."

In 2007, Sorrentino, a resident of Curtis Terrace, was divorced from Saverio Sorrentino of Newtown.

Last month, the boy was reported missing by his father. Despite an intensive search by several police departments, including searches of the mother's home, he has not been found and is now listed on the website for the National Center for Missing and Exploited Children.

Saverio Sorrentino told the judge he is convinced his former wife knows where their son is.

"Do you have any information of any kind of where your son is?" the judge asked her.

"No, your honor. The first time I heard he was missing was from my daughter in an email," she responded.

"The court does not find your testimony to be truthful," the judge told her.

Kevin Collins, the lawyer appointed to represent Kathryn Sorrentino for Thursday's hearing, told the judge he spoke with her privately and she maintains she does not know her son's whereabouts.

"She has indicated very clearly she has no idea where the child is and she would be more than happy to submit to a polygraph test," Collins told the judge.

He said Kathryn Sorrentino's 93-year-old mother, who has Alzheimer's disease, is at her home, and she is concerned the water will be shut off and they will run out of heating oil if she is not allowed to go home.

Sorrentino is to be back in court at 2 p.m. Friday, when the judge will ask her again about her son.
