Unable to withstand the attack, both fell unconscious. Murali took a wooden log and hit Viswanathan on his head, killing him on the spot. Later, they took Shobana to a private hospital in their autorickshaw. After learning that Viswanathan was dead, Murali surrendered at the Guindy police station. He was handed over to Nandambakkam police since the murder took place in their jurisdiction. After interrogation, police arrested Kannan and Vasantha also. Murali and Shobana are married for 10 years. Viswanthan is a father of two children.
