Now 57 years later, Terri Whitney sits in her home office in Panguitch, Utah, where stacks of paper and folders have accumulated.
Health records. Printed emails. Family photos. Newspaper clippings. Notebooks with dozens of dates and interviews jotted down.
They are all about Diane.
Whitney, 64, was only 7 when her sister went missing, but she remembers her well. How she wore her brown hair in curls. The shades of violet in her gray eyes. A freckle on the end of her nose.
“There is still a hole missing in our lives,” Whitney said. “My desire is to bring her home. I’ve wanted it ever since I was a little girl. To make everything right."
Since 2001, Whitney has been working to solve Diane’s case.
With the help of Dr. Bruce Anderson, a forensic anthropologist with the Pima County Medical Examiner's Office, and detectives Jared D’addabbo and Stuart Somershoe of the Phoenix Police Department's Missing and Unidentified Persons Unit, Diane’s case has been been active for about five years.
“I want to find her … to have her in Arizona, buried alongside mother and father,” Whitney said.
