One Monday morning in 2016, Mark and Jacoba Tromp, and their adult kids Riana, Mitchell, and Ella left their home and berry farm in Victoria, Australia. When the police searched their home a few days later, they found it unlocked, with their cards and phones left behind. It was later reported that Mr and Mrs Tromp were showing signs of paranoia and stress and had fled their home.
Mitchell seemed to the only one unaffected by the belief that the family was in danger, and had brought his mobile phone along with him. When his parents discovered it, they made him throw it out the window.
By Tuesday morning they had travelled almost 500 miles North to a town in NSW, and Mitchell left the family to go home. The rest of the family continued to travel, but then the two sisters left their parents.
They stole a car and reported their parents missing. They ended up separating, and Ella and Mitchell were the first two of members of the Tromp family to return home. Riana, on the other hand, had climbed into the back of a car. When the driver of the car discovered her, she was in a catatonic state, and didn’t know her name or where she was.
Eventually, the entire family were found, but no one could explain their strange behavior, which the police involved called a “massive meltdown.”
