As per the police, the accused had confessed to having killed her mother-in-law for money. The police, however, given a clean chit to Amarjit's husband.
Mohinder was alone at homes when she was murdered. Her other daughter-in-law, Kulwinder Kaur, had gone to visit a doctor, along with her son and daughter.
It was Kulwinder who had informed the police about the murder around 1.30 pm on May 4. Salem Tabri station house officer inspector Dharampal said from day one the police were suspecting the role of some acquaintance in the crime and later zeroed in on Amarjit, who spilled the beans when detained for questioning.
