GUJRAT, Pakistan -- A New Jersey resident whose daughter and son-in-law were gunned down while on a trip to Pakistan was named as the chief suspect in their deaths.

Muzaffar Hussain is suspected of murdering his New York native daughter Uzma Naurin, 30, and her husband, Saif Rehman, 31, in an "honor killing," the Daily Mail reported.

Naurin and Rehman were shot dead Nov. 1 when their car was ambushed near the northeastern Pakistan city of Gujrat. The car's driver and several other passengers were uninjured.

The couple -- who were living in Scotland but planning to relocate to the US -- were in Pakistan to attend a family wedding which Hussain was also attending. Hussain has since returned to his home in Jersey City, N.J.

Pakistani police spokesman Nasir Butt said that the 58-year-old cab driver is being treated as the chief suspect in the case.

Members of Naurin's family were unhappy about her marriage to Rehman, a friend of the couple told the newspaper. Naurin was married previously, but her first husband committed suicide. Naurin subsequently refused to enter an arranged second marriage with her dead husband's brother.
