Kenyan police have launched an investigation into the death of Venezuela's acting ambassador, who was found strangled in her house in Nairobi Friday. Nairobi Police Commander Anthony Kibuchi said they suspect 57-year-old Olga Fonseca Jimenez, who was the Charge de Affaires, was murdered but did not give further details. Fonseca was found dead in her upmarket Runda residential estate in Nairobi. The police official said four domestic workers who were sacked by Fonseca recently were held for questioning. "We have launched investigations to establish the cause of the diplomat's death. We are questioning some of the domestic workers at her house and would let you know the full details after the investigations," Kibuchi said. Kenya's ministry of foreign affairs said in a statement that it was shocked to receive the news of the death of Fonseca.
