As he was convicted of wasting police time, Paul Meehan, a neighbour of Tia Sharp's grandmother, remained impassive as the verdict was delivered.
But as the hearing was adjourned he sat down and buried his head in his hands.
The last confirmed sighting of Tia was on Thursday August 2 at 4.30pm.
On Monday August 6 as the missing 12-year-old's family were frantic with worry, Meehan told police he had seen her walk past him the previous Friday while he was in his garden.
