A lawsuit launched in 2010 has uncovered new evidence in the Elizabeth Bain murder case.
Court documents reveal a handwritten note by retired homicide investigator Brian Raybould could challenge the police timeline of the case.
Bain's boyfriend Robert Baltovich was found guilty of second-degree murder in 1992. He spent eight years in jail and eight on bail before he was acquitted in 2008 during a retrial.
Baltovich's lawyers have asked the courts to look at a note written three days after his arrest in November 1990.
The note, written by Raybould, details a meeting with forensic experts regarding blood that was found in Bain's car.
It challenges the police theory that Baltovich had allegedly transported Bain's body to its final resting place three days after she was murdered.
The note was discovered by Baltovich's lawyers in 2013.
Bain was 22 at the time she went missing in June 1990. Her body was never found.
