Police investigate death of Perth DJ

Police are treating the death of Perth DJ Jaime Fernandez as a homicide and are seeking information from the public to help with the investigation.

The 41-year-old DJ and event promoter was found at his North Beach Drive apartment in Tuart Hill last Tuesday with no signs of forced entry to the unit.

A post mortem had indicated he was killed between 10am on Saturday, July 16 and 8am on Sunday, July 17 from significant injuries, Detective Senior Sergeant Dave Gorton said.

Det Sen Sgt Gorton said that the level of injury and circumstances in which he was found led them to believe he was murdered.

"The injuries are to an extent that it is suspicious in nature," he said.

Chilean-born Fernandez moved to Australia with his parents in 1995.

He lived alone but had a wide social circle of associates that police are trying to speak to, Det Sen Sgt Gorton said.

Neighbours had reported not seeing Fernandez for several days, which led police to his home.

It's believed he was last in contact with friends on the morning of July 16.

Police are seeking any information to help with the investigation, including anyone who was in the area or saw suspicious activity around the North Beach Drive units that weekend.

Fernandez had two sisters, one who lives in WA, and his parents were travelling to Australia from their home in Chile.
