Rosa is in urgent need of your help!

Last year her son Luis died in an accident while bicycling the The Pilgrims' Way of St. Jacob on route N601 near Mansilla de las Mulas (Roncesvalles - Santiago de Compostela).
Her 24 year old son was found guilty for not adhering a traffic sign.
The fact apparently is, that traffic signs were not installed until after the accident.
Rosa is now searching for a photo which anybody might have taken by chance of the area, to proof that traffic signs were not present before the accident.
Here is Rosa's original posting.
