Before leaving the flat with the kidnapped child, Raghu had left a note demanding a ransom. The Federal Bureau of Investigation (FBI), which had also joined the investigations into the sensational crime, was tightlipped about the ransom demand so that the child could be rescued.
The Telugu community in the US had announced an award of $30,000 for information about the infant.
The double tragedy has shocked Satyavathi's husband Venna Konda Reddy, who retired as a mandal education officer in Prakasam district, also in south coastal Andhra Pradesh.
Meanwhile, Telugu Association of North America (TANA) said the body of Satyavathi would be flown home Monday.
