She only spoke up once, to confirm her name. Wasni was denied bail Wednesday.
Family members could be heard sobbing at times as prosecutors read out a two-page description of the murder.
Prosecutors say a teenage girl used a stolen machete and a knife during a fatal attack on a suburban Chicago Uber driver. "We hope that justice for Grant Nelson does happen, and we hope that the press will respect our privacy at this time".
Detectives believe Wasni - a high school student who lives with her single mother - was looking for trouble and took at least three Uber rides in the hours before the murder. The prosecutors called the act "heinous" and "not provoked in any manner".
"Help me, help me".
According to prosecutors at the hearing on Wednesday, the alleged attack began after 34-year-old Nelson began the route; possibly two minutes into the drive, the report alleges that Eliza attacked him from where she sat in the back of the auto. He managed to stop his vehicle and run into a condominium building lobby where he sought help. "I'm going to die", Nelson yelled, according Assistant State's Attorney Michelle Cunningham.
Wasni climbed into the front seat and drove away, but struck a median.
The Wilmette Patch reports that after brutally stabbing her Uber driver within minutes of getting in his auto, Wansi attempted to flee the scene of the carnage. A police report described Wasni striking her victim within minutes of entering his vehicle, striking him repeatedly on the right side of his arm, torso, head and chest.
Using Nelson's Uber app, police learned the fare was named "Eliza", the Tribune reported.
Officers would find Nelson lying in grass after following the trail of blood.
Nelson was then transported to an area hospital, where he later died from his injuries.
"You know, I think Grant was the kind of man who never knew his true life's calling", she told CBS Chicago. He never hurt anyone.

"On Wednesday, an Uber spokeswoman issued a statement, saying, "[Uber is] heartbroken by the loss of one of our partners, Grant Nelson. After the alleged theft, Wasni took the Uber driven by Nelson.
"He was doing everything he could to earn a living and this awful, bad thing happened to him", she said.
