'Chicago Fire' Season 4 Episode 17 Recap: Severide And Cruz Find A Baby's Remains In 'What Happened To Courtney'

The case of the week on “Chicago Fire” Season 4 Episode 17 involved a baby’s corpse discovered inside a house's chimney. Casey also faces a predicament in his campaign.

Previously on “Chicago Fire,” Casey (Jesse Spencer) was the focus of a propaganda campaign and pondered on his plan to run for alderman. The team also saved a man who was trapped inside a burning vehicle.

“Severide (Taylor Kinney) and Cruz (Joe Minoso) find a child's remains inside a chimney while investigating a possible carbon monoxide leak inside a home. In other events, Casey braces for the worst in his run for alderman while Alderman Becks continues to bad mouth him to the press,” states the“Chicago Fire” episode synopsis on TV.com.

During the latest “Chicago Fire” episode, titled “What Happened to Courtney,” the fire department went to a house which turned out to be empty. The team proceeded to check the air in the home and discovered that the carbon monoxide level was high. The leak apparently stemmed from the chimney and upon further investigation, they discovered that a dead body of a child was hidden in the structure. The corpse was blocking the chimney and causing carbon monoxide levels to rise.

The family that owns the home said that they bought it just a few months before and did not notice anything wrong with the place. They have been out of town for several days, so someone must have placed the body in the chimney while they were away. Severide noticed that the necklace around the dead child’s neck was included in the “Chicago Fire” case file of Courtney Harris.

Courtney was a little girl who wandered away while her parents were having a house party on the lake. Many believed that she drowned in the lake. Severide also remembered that the little girl was given a St. Nicholas train by her mother and recognized the toy when he spotted it again.

Subsequently, an investigator arrived who was furious at Severide for allegedly contaminating her crime scene. She was pressuring Severide to write down everything that happened when they first entered the home. Severide told the detective about the necklace and train, but she said that she needed to get DNA to confirm his theory. When they tried searching for Courtney’s family but they were nowhere to be found and have changed numbers many times.

Meanwhile in “Chicago Fire,” Casey’s campaign had an issue when he found out that he cannot do both jobs at the same time, writes BreatheCast. He consulted a political advisor for help.

This episode was directed by Jeffrey Hunt and written by Matt Olmstead. “Chicago Fire” Season 4 Episode 18 will air next on Apr. 5 on NBC.
