A former Univeristy-of-Minnesota student is pleading guilty to terroristic threats following an incident that forced the closure of Coffman Memorial Union last summer on campus. 35-year-old Jason Johnson of Minneapolis was accused of placing a bag filled with smoke flares and gas-soaked towels outside the building. The former engineering student will be sentenced next week. (Jan 21st) Johnson was enrolled at the university from 2006-2010.
