GUATEMALA CITY (CWNews.com) - About 1,000 people marched in Guatemala City on Wednesday, observing the second anniversary since Auxiliary Bishop Juan Jose Gerardi Conedera was murdered at his home.

    The group marched from Metropolitan Cathedral, where the bishop is buried, to a nearby church where a bronze memorial plaque was unveiled. The 75-year-old bishop was bludgeoned in the garage of his home on April 26, 1998, two days after releasing a human rights report that blamed most of the deaths in the country's 36-year civil war on the army and its paramilitary allies.

    Although human rights groups and Catholic leaders have insisted the investigation should focus on the link to the report, prosecutors have instead charged a priest living with the bishop, his housekeeper, and two members of an elite security unit in the crime.

    Many critics have been frustrated with the slow pace of the investigation, partly caused by the resignation of two prosecutors and a judge who have said they motivated by death threats against them.

    The UN Mission in Guatemala issued a statement calling the bishop an outstanding defender of human rights and revealed "the existence of new evidence about the possible involvement in the crime of people linked to illegal or underground security agencies."
