The smiling, pigtailed toddler in the gold heart top. A picture of innocence, and sadly the image many people will now recognise - Cleo Smith, the latest Australian child to vanish without a trace.
Four-year-old Cleo disappeared from her family's tent during the night at a campground north of Carnarvon, in Western Australia.
Police believe she was most likely abducted. On Thursday, the WA government announced a reward of up to $1 million for information about her disappearance.
Cleo is the latest missing child to grip the nation. And our fascination with every twist and turn of such cases can both help and be a curse.
Huge interest in the case
Cleo's case has drawn a high level of media and public scrutiny. Google is returning over 56 million hits on the child's name; multiple news stories appear daily from all main media outlets.
Largely, the public has been concerned for the child, hoping for a safe return.
However, social media has also gone wild with speculation, with the mother and stepfather being openly attacked.
Then there was William Tyrrell, the little boy in the Spiderman suit, who disappeared without a trace from his grandmother's house in Kendall, NSW in 2014. Sadly, what happened to William remains a mystery.
More recently, three-year-old Anthony "AJ" Elfalak, a non-verbal boy with autism, went missing from a rural property in NSW in September 2021. Fortunately, he was found safe and well after three days.
Clearly, everyone is hoping the same will be true of Cleo.
Why do lost children evoke such a response?
The public is so interested in missing children cases for a number of reasons, beyond concern for their obvious vulnerability.
Children represent our future. We are heavily invested in kids from both an evolutionary perspective, as well as psychologically.
When a child goes missing, the event represents a threat to our sense of predictability, order and security in the world. Consciously or not, we have a desire to fix this, which can only occur if an abducted child is returned.
Without the child being returned, the need for certainty in our own life is difficult to restore. Children, after all, continue our gene pool and blood line. Without them, we are only one generation away from extinction as a species.
News of the abduction of children also occurs in real time. And the internet is both helpful and a curse.
Bad news spreads fast. This can be of great assistance in raising public awareness and engaging members of the public to do some basic detective work.
News spread online can also jog the memories of potential witnesses. The information collected this way can significantly help police.
However, the minute-by-minute analysis of child abduction cases can have a major impact on our collective psyche.
Such non-stop coverage often occurs with prurient, distressing detail, tearful press conferences and what seems to be an interminably long waiting game, with generally no news or tragic outcomes to report.
In real time, we are taken into the very private lives of the child's family, their homes, their toys, their backyards and their activities.
This invasion of personal space further reinforces the public's strong sense of identification with the family. We relate to their grief, their anger and their anxiety. It could, after all, be our child who has been taken.
There is an emotional connection and generally speaking, enormous empathy for these families. In a sliding-door moment of time, these families are plucked from obscurity, to find themselves front-page news, spreading like wildfire through social media.
We also share their fear for the worst.
Then there are the conspiracy theories
Keyboard warriors vent their anxiety and, at times, anger, online. Wild stories with sinister undertones circulate and propagate, laying blame at the feet of family members, associates or the police investigation.
For some, this provides a sense of identity and security. By expressing opinions online, the keyboard warrior feels a greater sense of connectivity with the victim, even if they live on the other side of the country, or on another continent.
By reaching out in this way, albeit at times in an offensive and cruel manner, they feel a sense of empowerment and control.
However, these conspiracy theories can have a devastating psychological impact on those involved. And the lack of awareness of this impact on individuals and families truly beggars belief.
These conspiracy theories can also impede the investigation, as they're a major distraction.
There's collective grief
When the investigation ends with a tragic outcome - or for some, arguably worse, no outcome - the collective grief in our community can be immense.
This is linked with the strong sense of identification and fear we experience when a child is taken from a family.
It is the premature and unexpected loss of a child, even anonymous, through evil processes beyond our control that can trigger these strong reactions.
Fortunately, a child disappearing without trace is rare in Australia, and the entire country is now holding its collective breadth, hoping Cleo is found soon.
Having worked with many crime victims, including families who have lost loved ones and whose cases remain unsolved, until this mystery is solved, we know the pain will be enduring for those closest to this little girl.
So I would hope for kindness and consideration in how the community discusses this case - including on social media. Words have power, so please choose yours carefully.
