WASHINGTON, Sept. 28 (Xinhua) -- Five people were killed, including the suspect himself, in a workplace shooting on Thursday afternoon in Minnesota, local TV reported.
The gunman, a discontent ex-employee of Accent Signage Systems, killed his ex-boss and three others before turning the weapon on himself, according to the report.
A high-ranking law enforcement official told Minneapolis-based Fox 9 TV that the shooter arrived at the office Thursday afternoon after being terminated from his job earlier in the morning and started shooting after 4:45 p.m. (2245 GMT).
Four others were hospitalized because of injuries, three were in critical condition, said Fox 9 TV.
