RCMP plan to release another piece of the puzzle Friday in what the police force describes as a ‘bizarre crime scene' in New Annan.
A news conference will be held Friday afternoon in which police will lay out more details about what happened in a black Volkswagen Passat parked on the side of Route 2 in New Annan Sunday afternoon.
Police say Maurean MacDonnell, 36, likely died in the vehicle while it was pulled over on the side of the busy highway.
Rick MacLean, 47, most likely died as the result of injuries he incurred while he was in the same vehicle.
However, up until now police have refused to describe their deaths as murder, murder suicide or something completely different.
RCMP Sgt. Andrew Blackadar says the public should not expect any startling revelations to be released Friday.
"Nothing at this point is 100 per cent certain," Blackadar told The Guardian Thursday.
"From what the investigators were telling me today - and it was very brief - they have some things they can give to us to see what we can get out there to the public."
RCMP investigators will be meeting Friday morning at the East Prince RCMP detachment near Summerside.
A news conference will be held in Charlottetown in the afternoon.
Police are not yet saying how the pair, who were both estranged from their spouses, died even though a post-mortem examination has been completed on both.
A forensic pathologist completed the post-mortem on MacDonnell, of Kinkora, and MacLean, of Charlottetown, at the QEII Health Sciences Centre in Halifax on Tuesday.
Police say the cause of the deaths is not being released pending results of further investigation and consultation with other forensic specialists.
Investigators have revealed that police seized a knife in the car in New Annan. They would not say whether the knife was used in one or more of the deaths.
Nor are they ready to categorically rule out the possible involvement of a third party despite the fact police have no suspects, no persons of interest, are calling the deaths an isolated incident and have reiterated there is no risk to the public.
MacDonnell was recently estranged from her husband, RCMP Const. Stephen MacDonnell, an officer with the East Prince detachment.
RCMP interviewed him right after the incident, but police say they don't believe he's involved.

On Sunday afternoon, a passing motorist found MacDonnell dead in the Passat that was on the side of Route 2 in New Annan with the four-way flashers on and a door open.
MacLean was also in the vehicle behind the wheel. He was taken to Prince County Hospital in Summerside where he died from his injuries.
Police said the two knew each other.
Funerals for both individuals will be held on Saturday.
Blackadar said the RCMP has received numerous tips, some of which have been helpful as the police try to create a timeline of where MacDonnell and MacLean were and what they were up to during the final hours of their lives Sunday afternoon.
Anybody with any information, no matter how small or trivial it may seem, is being asked to contact the East Prince RCMP.
"The tighter the timeline on the two deceased people, from after lunch until 3:30 p.m. Sunday afternoon, the more gaps we can fill in and the better it is for everybody, including the public."
