The Windsor Police Service is renewing efforts in the 30-year-old cold case of Diane Dobson.
Dobson, 36, was last seen on February 14, 1995 walking down Prince Road. The next day her body was found in a ditch at Windsor's Brighton Beach.
An investigation revealed that a blow to the head was the official cause of death. Her killer was never identified.
Now, investigators are reevaluating evidence, conducting new interviews and renewing calls for information.
"We are pleading to the public and people from 1995 who were friends and family of Diane Dobson to come forward and speak with us. We know that there was, at that time, some fear of retaliation or people were just worried about speaking to the police at that time we want them to come forward and tell their story today," said Sergeant Ted Novak.
As part of this process, evidence is being resubmitted for DNA analysis.
"Right now there is some DNA but there wasn't enough to generate a profile. Now we're hoping with advances in science that a profile can actually be compared to the databank," said Novak.
The Windsor Police Major Crime Unit is currently digitizing all old paper reports and reviewing the autopsy, old interviews and evidence.
Investigators urge anyone with information (including those who have previously spoken to police) to call the new Cold Case Review Unit tip line at 519-255-6700, ext. 4305.
