Police have cast a nationwide and international call to women linked to a man whose wife was found dead in suspicious circumstances near a lawnmower.
Police on Friday said Robert Crawford - reportedly a decorated RAAF pilot - had "connected" with women across Australia and around the world, including some via dating apps, before his wife's death in the early hours of July 30.
Detectives have asked the women to come forward and assist what they have confirmed is a homicide investigation.
The body of Frances Crawford, a 49-year-old mother-of-three, was found near a mower at the bottom of a retaining wall at Upper Lockyer, west of Brisbane, about 3.40am.
Emergency services had been called to a report of an incident involving a ride-on lawnmower.
Police said Mr Crawford called triple zero, was the last person to see his wife alive and was at the property on the night she died.
He is assisting police who have not confirmed that he is a suspect.
Police have appealed for public information, including from multiple women they believe have had contact with Mr Crawford.
"We believe there are women who were involved in relationships with Mr Crawford who may have information about Frances that will assist with this investigation," Detective Superintendent George Marchesini told reporters.
"Mr Crawford may have met these women on dating applications and through his personal and professional life.
"We can say that Mr Crawford has connected with women nationally and internationally."
Mr Crawford had allegedly met with women in Italy, the US, Papua New Guinea, Guam, Afghanistan, Japan, Malaysia and New Zealand.
Closer to home, he also allegedly connected with women in Western Australia, the ACT, Northern Territory, NSW, Victoria and his own state of Queensland.
"The purpose of today is to appeal for public assistance as investigations continue into the circumstances," Det Supt Marchesini said.
"We're confident that there are people who are out there who have vital information."
Ms Crawford's death was initially deemed suspicious.
"We are now alleging that she was murdered," Det Supt Marchesini said.
Police said Mr Crawford had located his wife's body in the early hours before calling emergency services.
Asked if he thought it was unusual Ms Crawford might have been using a mower at 3am, Det Supt Marchesini said: "emergency services have attended at that time.
"Any situation like that, police are going to undertake further investigation.
"There's been extensive forensic testing ... as a result of that we can't, at this stage, definitively determine how she has come to be at the bottom of that retaining wall."
There were no domestic violence orders in place when Ms Crawford died but police had attended the property in July 2023.
"That was in regards to a call for service in regards to domestic and family violence," Det Supt Marchesini said.
Police said Ms Crawford's family were "looking for answers".
