Major Crime squad officers have been called to Bunbury to investigate the sudden death of a man in College Grove earlier this week.
About 2.45pm on Monday police responded to a call regarding an unconscious man on Darwin Way.
St John Ambulance personnel also attended the address, but despite their best efforts, the 38-year-old man could not be revived.
He died at the home.
Bunbury detectives, along with officers from Major Crime, are continuing to investigate the circumstances surrounding the man’s death.
The death is being treated as suspicious until determined otherwise.
A post-mortem will be conducted on Thursday.
Police have spoken to a number of neighbours as part of their investigation.
No one has been arrested over the death at this stage.
Neighbour Marshall Drummond told Channel 7 he heard screams for help on Monday afternoon and performed CPR on the man, a friend of his, for 25 minutes.
The Mail understands the death is the second tragedy for the family in the past six months, after the man’s son drowned in a neighbour’s pool last July.
Anyone with information that could assist with the investigation, or who saw or heard anything suspicious in the Darwin Way, College Grove area on Monday, is asked to call Crime Stoppers on 1800 333 000 or report the information online at crimestopperswa.com.au.
