Muthulakshmi, aged 37, killed her husband, Arumugam by smashing his head with a grinder stone. Allegedly, the man has a habit of coming home drunk and often fights with his wife. On Sunday, when Arumugam came home in an intoxicated state and picked up a quarrel with his wife for not cooking non-vegetarian dishes, she hit him with a log and then smashed his head with a grinder stone. A case was filed against Muthulakshmi, who is on the run.
