Additional District Sessions judge Ravinder Kumar yesterday convicted Sanjiv Kumar to life imprisonment after holding him guilty under IPC section 302 (murder).
A fine of Rs 5,500 was also imposed on the convict.
According to government counsel Jitender Tyagi, the victim, Ram Prasad, was shot dead by Sanjiv in 2009 after the former objected to the relationship between the convict and his wife Sarla.
A case was registered against Sanjiv and Sarla. Sarla was acquitted for lack of evidence, he added.
