Saanvi Venna has been missing since her 61-year-old grandmother, Satyavathi Venna, was murdered inside the apartment in King of Prussia. Investigators believe the abduction happened between 8 a.m. and 1 p.m. Monday.

Police have not said if there are any suspects. The Citizens Crime Commission and an Indian organization called the Telugu Association of North America are offering a $30,000 reward.

Upper Merion Township police say the girl's father, Venkata Konda Siva Venna, and mother, Chenchu Latha Punuru, immigrated to the U.S. from India in February 2007 and moved to the apartment in June.

The grandmother arrived in July and was scheduled to return home in January.
