Coimbatore: A special court here on Thursday sentenced three persons to double life term and another 10 years rigorous imprisonment for murdering a man and his daughter besides injuring two women near Sulur on the city's outskirts in 2014.
Special court judge Gunasekharan said the sentences have to run consecutively.
The prosecution case was that the trio - Uday Kumar (19), S Paramasivan (23) and Syed Abdul Khadar (29) - had done to death powerloom unit owner Rakiappan and his daughter Vanitha in their house in Kumarapalayam on the night of December 24, 2014.
Kumar and Khadar were employed in the powerloom unit run by Rakiappan.
As Rakiappan had refused to part with money sought by Kumar, the trio stabbed him.
The three also killed Vanitha as she was witness to the murder.
The prosecution contended that the three also attempted to kill Rakiappan's wife and younger daughter, who rushed to the spot after hearing their screams. They, however, escaped with serious injuries.
