Carmarthen's County Hall will be lit up in pink this evening in tribute to the ongoing search for April Jones.
The five year-old was abducted four weeks ago while playing with friends near her home.
When April vanished police forces from across Wales and England, the fire service, RNLI and coastguard searched day and night in the hope of finding her.
A month on and 17 specialist search teams, including 120 officers, are still scouring the surrounding area looking for the smallest of clues which could lead to the whereabouts of April.
Local people also joined in the hunt and as the days and weeks went on they also wore pink ribbons, April's favorite color, as a sign of hope and solidarity.
