In Bengaluru, on Friday night, five members of a family, including four adults and a nine-month-old infant boy, were found dead inside a house in Thigalarapalya off Magadi Road, according to West division police.
A two-and-a-half-year-old girl, Preksha, was found unconscious in the midst of highly decomposed bodies and was rescued by the police.
The girl has barely survived the trauma and is now undergoing treatment in a hospital.
The police say that the girl might have fallen unconscious after starving for almost four days.
According to the investigation, the police have found that all four adults alleged killed themselves by hanging from the ceiling in different rooms after closing all doors and windows of the house.
They also suspect that the adults died around four days ago.
The Deputy Commissioner of police (West), Sanjeev M Patil said, "The baby was found dead on the bed. We have sent all the dead bodies for postmortem and the investigation has started."
The deceased are identified as Bharathi who was 51 (wife of Halegiri Shankar), Sinchana, 34, Sindhurani, 31, Madhusagar of 25 and the nine-month-old grandson (Sindhurani's son).
The rescued girl Preksha is Sinchana's daughter.
Halegiri Shankar, a journalist from a local newspaper arrived at his house and found the front door locked. He peeped through the window only to find his family members dead.
He had left the house some five days ago in a fit of rage, for a family dispute. The incident came to the limelight only after his arrival.
He reportedly had an argument with one of his daughters, who left her in-laws to stay with them.
A case of unnatural death has been registered at the Byadarahalli Police Station and they are trying to ascertain the reason behind the alleged suicides.
"The reason behind the extreme step of the deceased persons is yet to be known. Police teams are searching the house to know if they left any suicide note. Experts from the Forensic Science Laboratory are examining the scene", said DCP Patil.
