In August 2000, Walter Poirier of Lowell, Mass., arrived in Bolivia to serve in the Peace Corps, and his assignment required him to regularly travel the road between the Zongo Valley and La Paz. Volunteers usually aren't allowed to drive, so the 22-year-old was forced to use old, poorly maintained public buses and vans, or find rides with people he hardly knew.

Wishing the new searchers, luck and safety.
I hope everyone realizes what danger the crew are facing in that area.
