Three of a family, including a four-year-old girl, were found dead in their house at Convent Road near Pravachambalam in Nemom police station limits on Thursday.
The police identified the deceased as Parameswaran Nair, 58, his widowed daughter Lakshmi, 28, and his granddaughter, Devanjana. They suspect Mr. Nair to have entered into a suicide pact with his daughter. The duo could have fed Devanjana with food laced with poison, possibly a pesticide, before consuming the lethal substance themselves. Mr. Nair's bedridden wife was in the house at the time.
The police said Lakshmi had lost her job in the Gulf where she was employed as a nurse for sometime. The family were living in a multi-storied house which they had built from loans given by some local money lenders. Investigators suspect that debt had driven the adults to kill Devanjana and commit suicide themselves.
The police registered a case of unnatural death and investigations were on.
