Ambush on Carl Nussbaumer

"That's Officer Nussbaumer. Twenty-year decorated vet. Beaten to death. We think it was personal."

- Imada to Jessica Jones

The Assassination on Carl Nussbaumer was a trap planned by Trish Walker and Erik Gelden in order to expose Carl Nussbaumer's crimes.

Background
"If we can get him to admit it on video-" "It won't hold up." "It doesn't matter. I would put it online. It could trigger an investigation. I know it costs you, but you can see into people. You've seen into this cop. If he kills another kid, you will be the only person on earth who saw it coming."

- Trish Walker and Erik Gelden

In an attempt to find more money for gambling, Erik Gelden learned about Carl Nussbaumer who murdered several young drug dealers to steal their money and product. Gelden left an anonymous note for him, extorting the money from Nussbaumer in exchange for silence and he paid him even twice. Later, Nussbaumer was approached by Jessica Jones who knew about his crimes and wanted to infiltrate inside the NYPD Crime Laboratory. He refused to help her and attempted to attack her, only to be confronted by Gelden who forced him to help Jones.

As she was unable to take down Gregory Sallinger, Trish Walker was determined to take down another criminal and Gelden informed her about Nussbaumer and his crimes. Walker planned an ambush on Nussbaumer, as she will force him to admit his crimes, while Gelden would record all of this. Despite Gelden's skepticism, he agreed to help her and left another extortion note for Nussbaumer. He, on the other hand, acquired all possible information about Gelden and went to kill him.

Ambush
"You paid him off because you killed those boys." "It wasn't a payoff. I executed a sting to catch a blackmailer. But he got away. Until now."

- Trish Walker and Carl Nussbaumer

Erik Gelden successfully lured Carl Nussbaumer to the empty warehouse outside the town. While Gelden was recording everything on his phone, Nussbaumer entered the warehouse, intending to find and kill him. However, Trish Walker then recited all young criminals murdered by Nussbaumer, and he acknowledged his crimes. He mistakenly assumed that it was Jessica Jones and informed her that he came only for Gelden, not for her.

Walker stepped in and ambushed Nussbaumer, disarming him and forcing him to attack her with the taser, although Walker was able to fight back. Nussbaumer kept claiming that criminals he killer deserved, only for his confessions be recorded by Gelden. As they would use the footage as the evidence against him, Nussbaumer attempted to attack him, but he was stopped by Walker who hit him against a wall. However, the blow was too severe, as Nussbaumer's skull was broken what instantly killed him, forcing Walker and Gelden to run away, leaving his corpse behind.

Aftermath
"What if Nussbaumer's killer hits someone else?" "I'm not gonna kill someone else." "Not kill. Just rough up another bad guy."

- Erik Gelden and Trish Walker

Carl Nussbaumer's body was discovered by the New York City Police Department with no possible evidence about the murderer, except his body camera that recorded Nussbaumer's previous conflict with Jessica Jones. Imada and Defford were tasked with investigation and although they were unable to link Jones with Nussbaumer's murder, she still remained the main suspect. Despite not having enough evidence, NYPD was determined that Jones was guilty, so she was arrested and taken into custody.

Determined to divert any suspicions from Jones, Erik Gelden and Trish Walker decided to organize another attack, so Jones would have an alibi. Gelden managed to locate Jace Montero who was guilty in several arsons across New York City, and Walker confronted him. However, instead of just knocking out Montero, Walker murdered him as well before leaving, saying that he was worse than Nussbaumer. Considering Montero's murder, NYPD let Jones go and went on the hunt for Walker.
