Man, 28, who shot and killed two black bystanders in Massachusetts after stealing a box truck and slamming it into another car was 'fueled by white supremacy', DA says Suffolk County DA has released excerpts from journals belonging to Nathan Allen, 28, which detail how he was 'fueled by white supremacy’ In the profanity-filled journal excerpts, Allen wrote: 'White people are the worlds apex predators' He also wrote how 'the white race is superior' and how 'whites in the USA are waking up' to the 'fact' that black people 'know they are inferior to us' Allen killed two innocent black bystanders in a suburb of Boston on June 26 in what the district attorney called an 'execution'
