Are we doing enough to track down missing people? Jenny Karmas came home from work one evening to an unlocked, empty house. Although her husband Sam had left his keys, wallet and ute at home, he was nowhere to be seen. He is still missing. Around 35,000 people go missing in Australia every year. Nearly 1,600 remain missing long term. How do those left behind deal with the disappearance of their loved ones? Are we doing enough to support them? In the lead up to National Missing Persons Week, Insight reveals that there is still no adequate national system to track these people down. Speaking to families of missing people, police from missing persons units, as well as a person who has been 'found’, Insight looks at why people go missing and whether enough is being done to find them.
