 in 1988, should demarcate it. Although most community members did eventually return to their land, the situation in Mato Grosso do Sul remains tense even today, with continual land disputes, death threats and murders of indigenous leaders and community members by assassins ('pistoleiros') hired by local farmers. According to the Indigenous Missionary Council (CIMI), Mato Grosso do Sul reported the highest number of murders, general violence, and land disputes from 2003 to 2005. Suicide has also become a serious problem among indigenous communities, and the Kaiowá people in particular, among whom there have been over 150 suicides in recent years. The Kaiowá are nomadic people who have traditionally migrated in search of the land without evil. Thus increases in suicide may be in response to dire living conditions and modern encroachments on their lifestyle as well as an attempt to reach this promised land. At least 17 of the 60 isolated indigenous groups in the Amazon are in danger of extermination as a result of murders and other practices initiated by illegal settlers and agricultural companies.
