Five members of a family, including three children, were found dead at their residence at Cherupuzha in this district on Wednesday morning, police said.
According to preliminary investigation it appears to be a case of murder-suicide where the couple, who got married last week, killed the children and then hung themselves.
The children were found hanging from the staircase and the couple from ceiling fans in the house.
The three children were of the woman from her first marriage.
