MAJOR Crime detectives have interviewed a man captured on security cameras outside the Paralowie home of James Tun Tin on the night he was murdered.

MAJOR Crime detectives have interviewed a man captured on security cameras outside the Paralowie home of James Tun Tin on the night he was murdered.

The man has not been charged but detectives said he remained a "person of interest" in the April 20 murder.

Police now believe six Aboriginal men went to the Gerrard Ave home to steal cannabis growing in a backyard shed. After being disturbed, somebody murdered Mr Tin, 37, with a shot in the back.

Major Crime acting Superintendent Denise Gray said it was possible most of the men did not expect the murder to happen.

"It might be that these six people might have attended that premises not being fully (aware) of what might occur and I invite those people to come forward to police and explain their position," she said. "It may be somebody has been caught up in something that they didn't intend happening and their best opportunity is to come forward to Major Crime and explain their position.

"These were a group of people known to each other who were targeting premises. Whether they consistently did it together each time or whether there are other players, we're not sure."

A red Hyundai Excel seen outside Mr Tin's home that night was later found partially burned at Thompson Beach, north of Paralowie. Detectives also have information that a silver Holden Statesman was at the scene when the Hyundai was burned out. Both cars were seized for forensic testing.

Police have interviewed the registered owners of both cars, who were "not persons of interest as such" but their associates were, acting Supt Gray said.

"We need information from the community, in particular any members of the Aboriginal community who may know something," she said.

In 2010, three men smashed into a Sturt home unit and shot and murdered Karen Hodgson in front of her three children for a few cannabis plants found growing in a shed.

A Ridgehaven man, 38, suffered deep cuts to his face and arms when slashed with a samurai sword during a home invasion by thieves looking for cannabis.

The attacks prompted acting Supt Gray to warn of the dangers of growing cannabis. "It is a very dangerous occupation to grow cannabis at your premises; it does lead to murder," she said.
