A couple convicted of raping their granddaughters must remain under house arrest while a judge decides whether they deserve a new trial.

Raymond and Shirley Souza, both 66, have spent five years under house arrest and seen two appeals rejected since they were convicted in 1993.Superior Court Judge Elizabeth Dolan extended the restriction order Monday but did not say when she would rule on the motion for new trial.

Although sentenced to nine to 15 years in prison, the Souzas have been allowed to remain at home as they appeal. Their request for a new trial is based on the claim that their original attorney misrepresented them.

The Souzas were convicted of raping two granddaughters, 3- and 4-year-old girls who told of being forced to touch the private parts of "Grammy" and "Papa." Experts found physical evidence consistent with sexual abuse, but no conclusive proof of it.
