Four Tanzanians have been sentenced to death by hanging for killing a 10-year-old albino boy last year, reports IOL. The court convicted them of murdering the boy and removing his head and legs. The ruling brings to seven the number of suspects sentenced to death for the murder of albinos in Tanzania. Since 2007, more than 50 albinos, many of them children, have been murdered and their limbs and organs sold to witchdoctors who use them to create charms meant to bring wealth and good luck.
