JMO, if Leah is in a shallow grave somewhere maybe there's a chance she'll be found. It's getting into the time of the year more dog walkers, hikers, cyclists, joggers, campers are about and starting to go that bit further than the winter months. There's also a lot more activity, Easter egg hunts, picnics, outings, Scouts, Brownies, voluntary community work, forestry workers, surveyors, foragers etc. Maybe someone will see or find something. I hate to think so morbidly, the thought of someone being left like that genuinely upsets me, there's a terrible cruelty in denying someone a proper burial.
