Vic pathologist describes gunshot death

The expert who autopsied a 36-year-old man allegedly shot dead by his father-in-law has told a Melbourne court about the abdominal gunshot wound that killed the victim.

Maxwell John Pain is accused of shooting David Paris in June 2014, with prosecutors alleging Pain thought Mr Paris was having an affair with his wife.

Forensic pathologist Matthew Lynch told the Supreme Court of Victoria on Wednesday that Mr Paris died from a gunshot wound to the abdomen that damaged his skin, bowel, kidney, pancreas, a rib and a major artery, with some fat protruding from the gunshot wound.

Mr Lynch said Mr Paris would have been shot at a range of between a metre and five metres, but closer to one metre.

He said he was only able to give a rough range because of a number of variables.

He said Mr Paris' black and red zipped vest and white singlet had "circular defects" and blood stains.

Mr Lynch said there was no evidence of an exit wound from the gunshot.

Last week, during the trial in front of Justice Michael Croucher, the court heard Pain was a licensed gun owner and kept guns at his property for hunting animals.
