"The only information we have is that my aunt (Satyavathi) has died and the baby Venna Sravani is missing. Our only concern now is the safety of the baby. We want Sravani to be traced at the earliest and request the US government to put in good efforts in this regard," Satyavathi's son-in-law Srinivasa Reddy and other relatives said.
Satyavathi from Guntur district was killed when she apparently tried to resist the abduction of her 10-month-old granddaughter from their apartment in Pennsylvania State in the US on Monday.
The police and the FBI have launched a massive manhunt to find the assailants and the kidnappers.
"It is three days since the incident happened. We are worried. The baby should not be harmed and they (abductors) should release her safely," Reddy said, adding Satyavathi's body was likely to be brought to India on Saturday.
Satyavathi had arrived from India for a visit in July and was scheduled to return home in January. She was babysitting the child.
The parents of the child-- Venkata Konda Siva Venna (father) and Chenchu Latha Punuru (mother)-- had emigrated from India in February 2007 and have previously lived in San Antonio Texas, Troy Michigan, and Cleveland Ohio. In June this year, they moved to King of Prussia in Pennsylvania.
