Two people were pulled from a pipe at the Enbridge Willow River pipeline crossing Sunday in northern Minnesota. According to a press release from the Northern Lights Task Force - comprised of northern Minnesota law enforcement agencies - the Aitkin County Sheriff's Office learned of two people who climbed inside the east end of the pipe. Officials say the pipe was capped at one end, which created a trapped air environment that reached nearly 130 degrees with limited oxygen. According to officials, a firefighter put on a Self Contained Breathing Apparatus and tried to reach the two people, but they refused to come back with him.
