Investigators say a woman they believed might have been killed in 1954 and found along a Boulder creek actually has been living in Australia for the last 46 years.

The Boulder County sheriff's office announced Thursday the woman they thought was the most likely candidate for Boulder's infamous "Jane Doe" murder case was located last week.

They found her after "a bit of dumb luck" through an Internet contact in Queensland, Australia.

Investigators thought Katharine Ferrand Dyer, now 84, might have been the victim in the unsolved homicide.

The sheriff's office says they're relieved Dyer is alive but discouraged that they're "back to square one" with their investigation.

The sheriff's office reopened the "Jane Doe" murder case in 2004.
