Legendary late CM MGR's foster son-in-law K Vijayan (53), alias Vijayakumar, was murdered here on 4 June, 2008.
A preliminary probe by police had indicated a dispute over control of properties bestowed by MGR to his family as the motive behind the crime.
In 2008, CB-CID, which probed the case, had said that the murder was allegedly masterminded by a police constable at the behest of N Banu who was also a close relative of the victim.
She had suspected Vijayan to be the brain behind her brother who was working against her interest. She allegedly decided to do away with Vijayan and conspired with a constable Karuna. She had allegedly paid him Rs four lakh to murder Vijayan.
Karuna had allegedly hired five men to murder Vijayan. While two followed Vijayan's car in a motorcycle, others toed the victim in another car.
