Frightened co-workers hid every where they could scrambling into closets and to the snow-covered roof for safety until police could reach them and bring them out safely. They were communicating with trapped employees by text and would locate them, then take a team of heavily armed police and swat into the building to rescue them.
It is being reported that two of those killed were found in the parking lot outside the plant.. One victim and the man believed to be the shooter were found inside, along with three weapons , an assault rifle, a handgun and a shotgun.
Names of the victims were not immediately released. Police said two of the injured were in critical condition and two were in fair condition. One was treated at a hospital and released.
