The man who admitted to police he drove his car and hit a 15-year-old boy on purpose made his first court appearance Monday.
New information revealed the driver threatened other members of the Somali Muslim community before, and people said they're still frightened.
Members of the Somali community in Kansas City said they were well aware of the suspect, Ahmed Aden, saying he moved to the city just six months before.
A police report showed Aden tried to use his car and a gun to attack others in the Northeast Kansas City community.
It happened on October 25 outside a shopping plaza on Independence Avenue just down the street from his home.
The report showed that Aden threatened one person with a gun and fled, hitting another car.
Police said weeks later the same person rammed his car in to 15-year-old Abdisamed Sheikh-Hussein. The teen later died from his injuries. The FBI later launched an investigation in to whether it was a hate crime.
Aden told police he used his car intentionally, but Sheik-Hussein was not the intended target.
People in the Somali community didn't want to go on camera but said they saw the suspect often.
The police report confirmed Aden wrote the "Quran is a virus worse than the disease Ebola" on the back of his car.
People said they saw Aden at the Garwaqo restaurant, also off of Independence Avenue, several times on Thursday. The person working the counter said Aden was two dollars short on his bill. The worker said Aden returned to pay the rest of his tab just 30 minutes before he told police he hit Sheikh-Hussein with his car.
The teen's uncle said they believed Aden worked alone, but they are still concerned as a community.
At a prayer vigil, Sheikh-Hussein's sister, Hafsa Hussein, spoke about her younger brother.
"He was a straight A student in academics and athletics," Hafsa said. "He was very, very aware of his culture and faith."
At a court appearance Monday, the judge set a $250,000 cash bond for Aden.
Sheik-Hussein's uncle said the bond concerned the community. They feared Aden would be able to pay the amount and harm someone else.
Aden's expected back in court on December 22.
