Flanagan offered a variety of motives before he killed himself Wednesday: A rambling 23-page manifesto sent to a national news network described his ambush as revenge for the killings of nine black people inside a church in South Carolina, which prompted federal hate crime charges against a white suspect.
On social media, Flanagan claimed his victims, 24-year-old Alison Parker and 27-year-old Adam Ward, had wronged him.
