Authorities have arrested a Washington State man who formerly worked at the University of California at Santa Barbara on suspicion of making a bomb threat and harassing the institution, The Tri-City Herald reported. The action follows an investigation of elaborate stories posted on Craigslist and e-mailed to the university by Neil Baker, a former engineer there. In one story, a mass suicide is described at the university. In one online image, Baker is shown in a mask, holding a rifle. The various comments suggest that Baker believes university officials have a vendetta against him.
