Blood samples of J Krishnaiah and Gopamma, the farmer couple from Khammam district of Telangana were collected by team from the Forensic Department of AIIMS, led by Dr Chittaranjan Behera, at the Ministry of External Affairs.
"These samples will be tested at AIIMS Forensic lab and Central Forensic Science Laboratory (CFSL) and matched with Geeta's samples, already stored at CFSL to confirm the claim made by the family," a senior government official said.
Doctors team will submit their report of the findings to MEA within a month.
Krishnaiah and his wife, residents of Patamata Narasapuram in Julurpad mandal of Khamam in Telangana, had also gone to Bhopal in Madhya Pradesh where 24-year-old Geeta is staying at an institution for the hearing-impaired.
