Homicide Squad detectives investigating the stabbing murder of 49-year-old David McArthur at Sanctuary Point in July have released CCTV vision of a vehicle and undertaken a coordinated search of waters at Sanctuary Point.
About 8pm on Sunday, July 25 emergency services were called to the Palm Beach Caravan Park on Ethel Street, Sanctuary Point, following reports of a stabbing.
Upon arrival, officers entered a cabin and found Mr McArthur with a stab wound to his chest. Despite officers attempting CPR, he could not be revived and died at the scene.
Initial inquiries were conducted by officers from South Coast Police District and detectives, before detectives from the State Crime Command's Homicide Squad took over of the investigation under Strike Force Frawley.
On Tuesday (October 12), strike force detectives returned to the South Coast to conduct a public appeal for information as part of ongoing investigations.
Acting on information, Homicide Squad detectives, assisted by officers from South Coast Police District, coordinated a search of waters around the Sanctuary Point Boat Ramp on Wednesday.
Police have also released CCTV vision of a utility and person depicted at the Sanctuary Point boat ramp on the night of Mr McArthur's death.
Homicide Squad, Detective Chief Inspector Wayne Walpole, said the search formed part of proactive investigations being conducted throughout the week.
"We have searched the waters around Sanctuary Point Boat Ramp - a location searched by investigators soon after David's murder back in July," Det Ch Insp Walpole said.
"We have also reviewed CCTV from the area, which depicts a utility and an unknown person at the location about 8pm on Sunday, July 25.
"Investigators don't believe the person or persons in this utility were involved in the murder of David McArthur; however, they may have crossed paths with those in the offending vehicle and we're keen to speak with them.
"I want to thank the community of Sanctuary Point who have been very forthcoming with detectives and use this opportunity to reassure them that Homicide Squad detectives remain dedicated to finding out what happened here three months ago.
"We now have several new lines of inquiry which we are exploring - our door remains open to anyone who wishes to speak with us and help David's family get the answers they deserve."
Investigations under Strike Force Frawley are continuing.
