Four suspected drug traffickers were arrested on charges that they helped orchestrate the killings of three Salvadoran politicians and their driver in Guatemala last month. Interior Minister Carlos Vielman said the suspects, three men and a woman, had ordered corrupt police officers to kidnap the lawmakers to recover money and drugs from their car. None were found. Four police officers arrested in the case were later killed in jail. A fifth officer remains in custody and one is at large, officials said.
