The couple used to quarrel often, which became a daily routine during the lockdown. Six months ago, both applied for divorce. On Friday around 4.30 pm the couple started to quarrel and after a point in time, Gokul took a knife from the kitchen and slit Keerthana’s throat. Police said Keerthana’s father Murahari tried to rescue her and got attacked in the process. Police said after slitting Keethana’s throat, Gokul dragged her out of the house by her hair and ran his car over her. He then sped away in the same vehicle even as aghast neighbours called the police control room.
