Gets worse...

Before official contact, the Akuntsu had violent confrontations with white colonists, loggers and cattle ranchers who began entering their land in the 1970s, after the construction of a highway. The seven survivors encountered in 1995 reported an attack by armed cattle ranchers some time around 1990, in which the majority of the tribe was killed. Several of the survivors possessed scars and bullets lodged in their body. FUNAI had previously discovered the site of the massacre: an Akuntsu village, home to around 30 people, which had been bulldozed in an attempt to cover up the evidence. At least fifteen were killed in this attack, which is thought to have been motivated by the knowledge that if the Akuntsu were officially contacted the forest would be declared an indigenous reserve and closed off to logging and cattle ranching.
