Andrew Hamilton's family say they were allowed to view his body and saw seven gunshot wounds to his left arm, abdomen, thigh and shoulder.

The 20-year-old was shot dead in the state of Oregon on Monday night by a police officer responding to reports of a burglary.

His brother-in-law says he often called to his house in Silverton in the middle of the night and may have taken a wrong turn on Monday night before banging on doors on a different street.

The police officer who fired the fatal shot is on administrative leave pending an investigation into the incident.

The Hanlon family have accused the police of closing ranks and refusing to disclose details of the shooting.
