Camilo Torres was more talented with the Eucharist than he was with a rifle. In his first combat after joining Colombia's National Liberation Army, the Roman Catholic priest turned leftist rebel was shot and killed.

On Monday's 50th anniversary of his death, some Colombians are reviving the memory in the hopes his life's journey from scion of an elite Bogota family to outspoken advocate for the poor can pave the way for an eventual reintegration of thousands of leftist rebels who may disarm under a government-brokered peace deal.

Torres' remains have never been found. But last month President Juan Manuel Santos ordered the removal and DNA testing of unmarked remains from a cemetery in northern Colombia where Torres was believed to have been secretly buried by the army.
