TODAY'S TMJ4's Julia Fello got the lucky assignment to go behind-the-scenes with the men in blue. She was even taught how to ram down a door with the stars of the show.
We asked fans known as "ChiHards" what they wanted to know before we got there. More than anything else they wanted Jesse Lee Soffer's take on the way "Linstead" ended. Many fans felt it was an abrupt ending for Sophia Bush's character when "Detective Erin Lindsay" left for the FBI.
"It's kind of interesting that he's kinda coming totally unraveled this thing in the beginning of the season where he killed the little girl," said Soffer, "There's no light at the end of the tunnel right now so it's going to be interesting for the fans too because its a side of him that we haven't seen."
Check out "The Now Milwaukee" Thursday night at 6:30 p.m. We'll take you behind the scenes of Chicago Fire.
