A 28-year-old Queanbeyan man killed in an apparent hit-and-run earlier this year got into a dark sedan shortly before his death, police say.
ACT police want to speak to the people who were in the vehicle that picked up Jyle Molloy on Morshead Drive on the night of Sunday, February 27.
Officers found Mr Molloy dead about 11pm that night on Piallago Avenue, not far from where he was seen entering the car.
His injuries were consistent with being hit by a motor vehicle.
At the time, police had little information about his death and asked the public for help.
On Monday, Acting Sergeant William Stevenson, of the ACT's major collision investigation team, said Mr Molloy had been walking along Morshead Drive before he got into the dark car near Royal Military College, Duntroon.
Sergeant Stevenson said the person or people in that car were "definitely the last ones to see Jyle alive — that's what we believe".
"Come forward and speak to us," he said.
"Don't be under the assumption that police think you've done something absolutely heinous.
"We don't know why Jyle got out of the car, we don't know what happened inside the car.
"I want them to feel free to come and speak to police."
Sergeant Stevenson also asked the public to rethink whether they had attended, or had guests who attended, a concert held in Canberra earlier that evening.
The Red Hot Summer Tour had been staged in Commonwealth Park, and interstate concert-goers might have left the event via Pialligo Avenue.
"[The public] may have some information about that. They may have some memory … that they haven't really thought of since then," he said.
'Driver attitude' a factor in high road toll
Mr Molloy's death is one of 18 on Canberra roads so far this year, the highest toll in 12 years.
The latest fatality involved a 24-year-old man whose ute struck a tree in Kaleen on Saturday night.
Sergeant Stevenson said his team was concerned by the high number of deadly crashes, and added that various factors were involved.
"One of those is definitely environment, another is definitely driver's attitude and, also, the physics of the vehicle itself," he said.
"What we've found is there's always a number of different issues, and each [crash] is very different to the next.
"You can never put your finger on any one, root cause: driver attitude, though, definitely has its role to play."
