Katrice Lee went missing while out shopping at a British military supermarket in 1981 (Picture: Family handout).
A woman has pleaded guilty to a malicious communications offence after impersonating missing toddler Katrice Lee online.
Katrice vanished on her second birthday on November 28 1981, on the outskirts of Paderborn in Germany, near the British military base where her father Richard was stationed.
Heidi Robinson, 40, appeared at Wirral Magistrates' Court on Wednesday and admitted posing as the toddler.
Ms Robinson pleaded guilty to using a public communications network to send a message that was grossly offensive, indecent or menacing on 3 November last year.
The case was adjourned until 30 October for a pre-sentence report to be prepared, which District Judge Nicholas Sanders said should include information on the defendant's mental health.
The judge said: "Clearly at the time you were not very well but, on the other hand, what you have now admitted to also caused some very real distress to people in this matter."
Ms Robinson, of East Way in Moreton, was given unconditional bail.
