Who is Nicole Muller? Zachariah Anderson's lawyer goes viral post cross examination of suspect's daughter 

Wisconsin man Zachariah Anderson is currently undergoing a homicide trial after being accused of stalking and killing Rosalio Gutierrez Jr., his ex-girlfriend Sadie Beacham’s new boyfriend.

Prosecutors have alleged that on May 17, 2020, Anderson went to Gutierrez’s Wood Creek apartment in Kenosha and brutally killed him with blunt force before disposing off his remains.

Amid the high-profile trial, Zachariah Anderson’s lawyer Nicole Muller went viral after conducting a cross-examination of the suspect’s teenage daughter.

On March 15, the 14-year-old took the stand to testify against her father and said that Anderson allegedly asked her to spy on Beacham and record “every single time my mother would get upset.” She claimed that the suspect “frequently” spoke Gutierez when she saw him.

The teenager also alleged that nearly a month before Gutierez’s death, Zachariah Anderson drove both of them to her mother’s place to spy on Beacham and Gutierrez through the window.

She claimed that her father also rummaged through Gutierrez’s truck and captured photos of the vehicle’s license plate and registration number before ringing the doorbell and fleeing the scene.

The girl also said that her father allegedly addressed Rosalio Gutierrez using a racial slur.

A video showing Nicole Muller cross-examining the teen in her testimony about Zachariah Anderson’s unregistered gun went viral online and left social media users divided.

While many praised the defense lawyer for rightfully handling a young witness, some were left unimpressed:

Muller’s cross-examination with the teen about the gun ended with the latter tearfully saying:

“I was threatened with that gun for your information.”

In another viral moment from the courtroom, a video of Anderson showed him clamping his mouth shut and putting his fingers on the mouth while looking towards his testifying daughter. Prosecutors then accused the suspect of signaling to the witness.

Meanwhile, Muller countered the claim by accusing the teen’s mother Sadie Beacham of using sign language to communicate with her daughter during the testimony. Beacham later said that she used mouthed “calm down” to her child as she was getting “sassy on the stand.”
