The death of Miguel Uribe, two months after the attack against him, marks a return to the worst period of political violence in Colombia.

Mr. Uribe, a presidential hopeful, was shot in June at a campaign rally in Bogotá in an attack that shocked the nation.

Miguel Uribe, who died on Monday, was from a prominent Colombian political family for whom the turbulence of the country's recent decades twice became personal tragedy. Uribe had been vying for his party's candidacy in upcoming presidential elections but died two months after being shot in the head at a campaign rally.
