Abetment to suicide case registered can it be take back or compromised

After engagement the girl's father started asking for money and pressuring our family for it. Thereafter we cancelled the marriage. They also threatened to file false case. The girl, her father and her mother all committed suicide and wrote that there is money lenders who are harassing and included the boy and their families name in it. Now the boy is in judicial custody. Other relatives of the girls family are saying we pay money they will take the case back. Is it possible?
