Emotional relatives of Bostic-Jones left bond hearing of the west side man accused of hitting and killing her.
"We just had to see his face," said Stormy Bostic, the victim's cousin. "You just have to see the person who took someone away from you that you loved so much."
Saturday afternoon in court, a judge set bond at $3 million for Juan Bello.
The 57-year-old West Side man is charged with leaving the scene of a fatal accident and reckless homicide, among other charges.
Dozens of co-workers of Bostic-Jones also packed the courtroom, many of them with black bands covering their badges.
They stood up when today's hearing began then left without comment.
"We're very grateful to the sheriff's department," said Tamika Bostic, the victim's sister. "They stood behind us. They were Nikkii's family too."
Bostic-Jones, 37, was hit by Bello's navy blue van as she made her way to work her shift at the Cook County Jail late Wednesday night.
She was then thrown into the path of a sheriff's squad car.
The married mother of a young daughter died moments later.
Police say Bello admitted to being the driver.
A friend also said that Bello was drinking alcohol prior to the accident.
State records show the Chicago man's driver's license was revoked in 2010 after a dui arrest in Iowa and before that one in LaSalle County.
Bostic's family says that just adds to their pain because Bello shouldn't have been behind the wheel in the first place.
"It's just a senseless act," Stormy Bostic said. "It's like he has no remorse."
In addition to the DUI convictions, Bello was issued at least two tickets for speeding, as well as running a red light.
He will return to court for a preliminary hearing on Monday.
