A three-year cold case review into the death of an Albany man who was struck and killed by a car on Mercer Road in Albany in 1991 has found the incident was probably murder.
Mark Edward Gregory was walking east on Mercer Road early on April 7 nearly 22 years ago when he was run down by a car and found dead 400m from the Lower King Road intersection.
In 2009, the unsolved hit-and-run case was reopened when fresh information came to hand, and last year Mr Gregory's children went public with a plea for more information to help police solve the case.
Now police believe Mr Gregory's death was most likely murder.
Albany Sen. Const. Norm Gill said police suspect more than one person was involved.
"As the result of the review and having spoken to members of the public and multiple calls to Crime Stoppers, we've found new lines of inquiries and as a result we've identified some suspects," he said.
Sen. Const. Gill said information provided suggested foul play and led police to believe the hit-and-run was a deliberate act.
"Someone out there knows exactly what happened," he said.
Mr Gregory's family, high school sweetheart Leanne and their children, Casey Greay and Zane Gregory, deserved answers on the death, which has haunted them for more than 20 years.
Mrs Greay, whose 19-month-old daughter Sienna was robbed of the chance to meet her grandfather, said news her father was murdered was "hard to hear" but she was thankful a breakthrough was made in the investigation.
She has set up a Facebook page titled Mark Edward Gregory RIP to get information about his murder.
"There'd be a bit of relief if we could finally lay Dad to rest," she said.
