Two people have been arrested in the murder of a New Jersey family -- a case that caused religious tensions.

The victims were members of an Egyptian Christian family -- a husband and wife and their two children. Their bodies were found in January.

The slayings caused animosity between Christians and Muslims in New Jersey. Friends of the victims speculated that the father had angered Muslims by posting in Internet chat rooms under the user name "I Love Jesus." And many Coptic Christians in New Jersey and elsewhere blamed Islamic extremists.

But prosecutors aren't giving a motive for the slayings. They've said robbery may have been a factor.

Someone used the victims' A-T-M card to withdraw thousands of dollars from a bank account in the days after the slayings.
