Delay in sentencing Vic farmer for murder

Maxwell Pain is due to be sentenced in Melbourne for murdering his son-in-law, David Paris.

A Victorian farmer who shot dead his son-in-law because he believed his wife was having an affair with him is due to be sentenced this week in Melbourne.

Maxwell John Pain, 55, was found guilty in April of murdering 36-year-old David Paris in 2014.

He was due to face the Supreme Court of Victoria on Tuesday, but his sentencing was delayed until Wednesday afternoon.

Pain said he didn't mean to kill Mr Paris, despite aiming the shotgun at his belly and pulling the trigger at close range.

Pain's obsession with the notion that his wife Tracy Bush was having an affair with Mr Paris drove him to shoot the man, his trial was told.

In June 2014, Pain grabbed a gun and texted his son-in-law: "I am on my way, Davey boy."

Ms Bush had recently told her husband she wanted a divorce and was staying at the home her daughter shared with Mr Paris.

The jury took almost four days to find Pain guilty of murdering his imaginary love rival.
