MONTVILLE: September 6, 2007. A Morris County congregation continues to mourn two missionaries killed last week in Pakistan in what appears to be a crime. The Rev. Arif Khan and his wife, Kathleen, were shot dead in their home last Wednesday in a residential neighborhood of the Pakistani capital of Islamabad, according to police. The Rev. Bart Carlson of Trinity Baptist Church in Montville, which sent the couple to Pakistan, expressed "shock and grief for the things we`re all feeling and still experiencing." The couple -- he was 58, she was 60 -- had worked in Pakistan for 11 years, according to a church release, ministering to a "small congregation" in Rawalpindi, and also took part in humanitarian efforts; such as distributing relief supplies in 2005 after an earthquake rocked the country. Memorial services will be held in Pakistan and New Jersey, but no dates were set Wednesday. Police said Khan was the pastor of a small church set up in a private house in Rawalpindi, a garrison city near Islamabad. Trinity Church released a statement this week that said police had arrested two people, Honey Havaid-- a former member of Khan`s Pakistan church -- and his wife, Fauzia, and were looking for a second man, Saeed Alam. An alleged affair had been reported as the initial spark for what happened. But the release said police had found no evidence to support that claim. The release also said the couple`s son was working with officials "to pursue justice through proper legal channels for this heinous crime against his parents and to restore the reputation of his father." The church`s statement said the family intends to bring the couple back. Carlson said family members asked that he receive all public inquiries. A State Department spokeswoman confirmed the deaths Wednesday but would not discuss details of the case out of privacy reasons and respect for the family. If a U.S. citizen dies abroad, the State Department confirms the identity, contacts the family and advises relatives on their options, which include an overseas burial or bringing the body back to the U.S. The family pays the costs. The State Department executes the family`s wishes and prepares necessary paperwork. Carlson said the Khans loved the Pakistani people. He described the husband as a "man of integrity" and the wife as a "devoted Christian wife," who worked hard, was wise and helped the poor. He cited a biblical passage on a wife of noble character as one that was a "good description of Kathy." This article contains material from The Associated Press.
