In Sgt. Mike Leary's office at Delta police headquarters, a stack of boxes, labeled Casey Bohun, reach the ceiling.
Leary was the last investigator - there have been several over the years - to delve into the troubling mystery involving the disappearance of the little girl.
Bohun was just three when she went missing from her North Delta home on Aug. 5, 1989.
Next week will mark 15 years since her disappearance, an anniversary of sorts the Delta police would like to end. But that won't happen unless the department receives new information that will lead to a conclusion in the case.
While there have been many theories floated since the little red-head disappeared, police believe she could be living elsewhere in Canada or the United States.
"It is possible Casey was abducted and we are seeking national assistance from he public as the 15th anniversary of Casey's disappearance nears," Delta police Const. Paul Eisenzimmer said.
While 15 years have passed, many agencies, including the Delta police that haven't forgotten her.
The Doe Network, as in Jane or John Doe, issued a reminder this week that Bohun is still missing.
"Around the time of the anniversary I've been trying to contact people, newspapers, trying to remind them of the disappearance," said Elizabeth Myers, a B.C. area director for the network, which is based in Louisiana.
The Doe Network, which also includes missing adults, has successfully concluded 21 cases of missing persons in the U.S., Canada, Australia and Europe. It is a volunteer group that assists law enforcement agencies in solving cold cases concerning unidentified victims and missing persons.
Several theories have emerged over the years into Bohun's disappearance. There have been alleged sightings, one which sent another group of investigators to Kamloops and Kelowna in the early 1990s.
But it wasn't until April of 2001 that the case was picked up once again. On that Sunday morning, Casey's mother, Barbara Bohun, 40, leaped to her death from the Patullo Bridge in New Westminster.
Friends say she was distraught over the loss of Casey so many years before and the more recent loss of her other two daughters. Social services took the girls from her over concerns about a disciplining incident.
Police say there was no suicide note.
Out of that incident came a chance for police to interview Bohun's boyfriend, the man who lived with her at the time of Casey's disappearance. In recent years, he had moved to Korea where he taught English at a college.
The boyfriend attended Barbara Bohun's funeral and it was then police investigators interviewed him. That interview raised new questions and police have so far been unsuccessful in their attempts to re-interview him. He is still in Asia, police said.
It was a warm August day in 1989 when Delta police officers responded to a call of a missing child. Casey Bohun lived with her mother and her mother's boyfriend at a home on 94A Avenue in North Delta.
Police were told at the time the couple had returned home the evening before, put Casey to bed and that was the last time they saw her.
A ground search escalated into a full-scale air search of the area. They searched for three days but found nothing. It was as if the toddler disappeared into thin air.
Police did not name anyone as a suspect, but say even today the only person they've ruled out is Casey's biological father, Donald Bohun. Former homicide detective Bill Jackson, one of the investigators who became involved in the file in the early 1990s, eliminated Donald as a suspect after he passed a polygraph test.
Delta police say the file is still open.
"We'd like to talk to anyone who may have information about Casey's disappearance," said Eisenzimmer.
