Helen and Wendy have never forgotten their sister, Elaine. 

In the early days after Elaine went missing they relied on news from family and friends about her whereabouts.

As the sisters got older, they broadened their search. 

Many of the leads Helen and Wendy have chased down suggest that Elaine met with foul play.

But others have given them hope that their sister might still be alive.

The first glimmer of hope came one day in 1999 when Wendy had a visitor to her home.

Searching for Elaine is a series from Out From The Cold, part of Happy Tuesday Productions.

If you have information about Elaine Johnson or Kerri Ann Joel, you can get in touch at Help Find Elaine Johnson or contact Crime Stoppers on 1800 333 000.

Searching for Elaine was produced by Kate Kachor and Sally Spicer, editing by Dan McHugh and Matt Haywood, artwork by Nic Watts.
