TUCSON, AZ (Tucson News Now) - Marana Police said Wednesday they have closed an almost 30-year-old murder case after confirming the identity of the victim on Tuesday.
The case began in November 1987 when authorities in Marana were led to the body of an unidentified woman who had been shot to death.
The case went cold after authorities were unable to identify her.
The case was reopened in 2009 and the killer was identified in November 2011 using DNA evidence as a convict who died in prison in 2005.
The Arizona Department of Public Safety Crime Lab used DNA testing to confirm that the victim was Deanna Lee Criswell from Spokane, WA.
Criswell's identity had remained a mystery until the Marana Police Department received a lead from a couple in Florida who were searching for their niece and read about the case on the internet.
Photos of the FBI's facial reconstruction and case details convinced them to contact the Marana Police, and their information led to the victim's mother, father and step-sister submitting DNA for testing.
