The five-member family had attempted suicide in Bavla, 25 km from here, police said adding that Ghanshyam Panchal (40) is the only person who is still alive, but is in a serious condition and undergoing treatment at a hospital here.
The girl, Krishna Panchal (17) and her mother Alka Panchal (38) died today at the V S Hospital, where they had been admitted yesterday, Bavla Police Sub Inspector (PSI) A Y Bhaloch said.
Preliminary probe to ascertain the cause of the extreme step has revealed that the family was under pressure from money-lenders. Police also recovered a suicide note, which was produced by Ghanshyam's brother.
Ghanshyam, who was in the business of construction, had not received money for the work he had done for quite some time, Bhaloch said and added that the victim had demanded money from one Prabhatsinh Gohil, who threatened him with dire consequences.
