Rajaiah's daughter-in-law S Sarika, had in April 2014, alleged that her husband Anil Kumar was having an extra-marital affair with the woman (Sana), and that they had two sons. Sana has now been named as fourth accused in connection with the November 4 case.
Police are yet to draw a conclusion on the exact cause of death of Sarika and her three sons, whose charred bodies were found at Rajaiah's house at Hanamkonda here on Wednesday, and they were probing all angles including suicide and murder.
All the three, who were inside the house when the four burnt bodies were found on the first floor of the building, were arrested last night after extensive grilling and remanded to 14-days judicial custody and are now lodged in Warangal Central Prison.
The complaint by Sarika's parents also alleged that Anil Kumar was "illegally" living with Sana.
