The issue was discussed several times with both the families and was settled by a panchayat earlier.
The matter came to fore on Saturday morning, when neighbours after hearing the cries of the victim rushed into the house. The victim had closed herself in a room, which was later broken to save her. But it was late by then as she suffered burns on almost all over the body.
Based on the complaint of Munni Devi, police have registered a murder case against in-laws including Devi's husband.
