In tonight’s Chicago Fire episode, Severide was finally enjoying two days off with his lovely wife when the worst happened. They were interrupted by the FBI. They needed an arson investigator and Special Agent Calloway told them about him. Severide was in the area. He was also one of the best at what he does.
They needed Severide because someone set fire to Judge Scanlon’s home while he was at the opera. The judge had a date night with his wife and they left their five year old at home with a babysitter. The babysitter didn’t survive the fire. And little Kaley Scanlon appeared to have been abducted.
Or at least that was the FBI’s fear. They feared that someone set the fire to take the little girl. They initiated a citywide search. It was all over the news and they were basing this search off of Kaley’s DNA being found on the backdoor. The sniffer dog picked it up. It had to be fresh. Severide took a look at the scene and he determined that it was arson.
The babysitter hadn’t died randomly. She had been killed. She was that child’s last line of defense and they took her out of the way to better their odds in a kidnapping.
This was well-planned. They knew about the date night. They knew about the babysitter. Severide has been filling in his wife about the case and she recognized the station that responded to the fire.
She offered to talk to them for Severide. He agreed. Kidd would later find out that a white Honda civic was seen idling by as they put out the fires. It was a good tip because they put out BOLOS for that make and model and it wasn’t long when they got an answer about it. It was soon found on fire. There was no one inside. The kidnapper even dared to taunt the dad by putting the scales symbol on the car.
The symbol alone proved motive. It had been the kidnapper’s plan to take the girl and punish the father. He was a judge after all. He’s been on the bench for fifteen years. He probably sent a lot of people to jail. Some felt the scales was a bit on the nose. The fire also reminded Severide of an old case that Van Meter told him about.
Kidd talked with Van Meter. He remembered a case in which the victims were doused with a paralytic so that the arsonist could watch them burn. Van Meter was investigating until the feds stepped in. They took over. They put Arthur Liddell behind bars. Van Meter ended up visiting Liddell in prison with Kidd at his side.
They questioned the man. He remained delusional. He didn’t feel remorse or pretend to. The lives he took was all about his artistry. He also said that scales was the newest artist signing off on his work. It wasn’t about the judge at all. It was merely a signature. The thing is that the person who knew about Liddell’s signature best was Agent Calloway. The ATF Agent joined the case. He recognized the signs. He dismissed them to himself and he couldn’t do that once Kidd informed Severide about everything.
Severide confronted Calloway about that case. The reason Calloway didn’t want to make a connection because what happened could be all on him. Calloway reluctantly admitted that they suspected Liddell had an accomplice. It was just a suspicion. There was no evidence at the time. Liddell never confessed to it. It would’ve lessened his own sentence if not helped him get out of charges altogether. Liddell still took full credit. His apprentice was older now. The original case was back in 2008. The new theory was someone taking revenge in Liddell’s name.
They knew this case would draw out Calloway. Someone that Liddell named as his chief adversary. He kept the agent up at night in fear because Calloway let the accomplice get away. He never pursued it. He never bothered to narrow it down out of a group of three. He finally talked about it and the feds narrow down who they were looking for. The accomplice was David Palmer. Judge Scanlon hadn’t been the judge on the case. He had been a prosecutor. He knew that Calloway would remember that.
Palmer has been reminding him about Liddell the entire time. He also left clues at his autobody shop. Calloway didn’t tell anyone. He followed the clues on his own because he felt he had to make up for his earlier mistake in letting the accomplice go free. Severide realized what he was doing. He and Kidd followed Calloway. They tracked him to the motel where he arrested Liddell. It was all about going down memory lane. They found Kaley. They rescued her. Calloway found where Palmer was hiding and he was murdered in a bombing at the motel.
Palmer’s body was also found at the motel. It looked like Palmer merely wanted revenge and to be a part of Calloway’s storied career. Calloway had been close to getting an award for his services. Only Palmer was paralyzed before the fire. He didn’t fight it at all. He wasn’t the killer. He was a scapegoat. Severide thinks someone set the perfect fires to target Calloway, but the FBI weren’t listening without Calloway there to back him up. This new arsonist was looking for an adversary and he found him in Severide. Not Calloway.
And right now there were only two people that believed in Severide’s theory.
THE END!
