The parents visited the nearby neighborhood, and all of their friends' houses, but failed to find the children. This is when they reported the Glenelg police, about the disappearance.

Many witnesses revealed to the police, that they saw the Beaumont Children, with a tall adult man. He was described as having an athletic build, with a tanned face, looking at his mid-thirties. The man was wearing swim trunks and was playing with the children.

As per a Big Footy article, published on December 12, 2012, an eyewitness described a girl, with the man, who was carrying an airline bag, which matched Jane. The witnesses also revealed that the Beaumont Children seemed very comfortable with the man as if they knew him already.

Additionally, as per another The Age article, published on April 22, 2007, Jane was seen by a shopkeeper, buying pastries and a meat pie with £1 note. Nancy recalled she gave the children only six shillings and sixpence, which meant the man had given them money.

As per The Sun Herald article, published on December 6, 1981, almost two years after the disappearance, the parents received two letters, with a postmark of Dandenong, Victoria.

One of the letters claimed to have been sent by the anonymous man, while Jane wrote the other. In the letter, Jane explained the uncomfortable lives of the siblings and told them that they were under the control of the man.

In the letter, the anonymous man appointed himself the guardian and was willing to hand them over, at a scheduled meeting place. The authorities at that time, believed the letters to be true. The Beaumont parents decided to work accordingly and visit the scheduled place, with a personal detective in disguise.

However, they found no one upon arriving at the place. A few days later, another letter arrived claiming to be from Jane. She said that the man had changed his decision, and kept the children because he found out about the disguised detective. As per The Sunday Age article, when a thorough forensic examination of the letters was done, they turned out to be fake.

As per an ABC News article, published on January 26, 2016, fingerprint examinations from the letter, matched it with a man, who had been a teenager at that time, hence it turned out to be false. No charges were taken against him, considering many years had passed since he faked out the letters.
