BOONTON, N.J. – A Pakistani-American man whose Pakistan-born wife was gunned down while they and their son walked along a quiet suburban street plotted the killing with another woman and told police his family had been attacked by a group of men who called them terrorists, authorities said Friday.

Kashif Parvaiz, 26, suffered non-life-threatening wounds in the shooting that killed his 27-year-old wife, Nazish Noorani. They were walking with their 3-year-old son to a relative’s house in Boonton when shots rang out Tuesday night. The boy was unharmed. The couple’s 5-year-old son was with Noorani’s family inside the house.

Parvaiz and Antionette Stephen, 26, of Billerica, Mass., both face murder, conspiracy and weapons counts. He also faces child-endangerment charges.

Parvaiz was arrested several days ago, authorities said. He was being held on $1 million bail. Authorities said they did not know whether he had a lawyer.

Stephen was arrested Thursday night in Massachusetts. She was arraigned Friday on a fugitive-from-justice charge and was being held without bail at a women’s prison in Massachusetts.

It’s not clear when Stephen might be returned to New Jersey. Attorney Meghan Spring, who represented her at her arraignment, did not immediately return a call seeking comment.
