Relatives of Casara are still struggling with her death as they pray for the recovery of her prematurely born daughter.
Sunday, the family headed to court to face those who police say are responsible for her death.
Most of Eva Casara's family left court today without saying a word after a judge denies bond for her boyfriend and his brother who have been charged in connection with her slaying.
"I'm surprised of his reaction. He seems cold-hearted," Melody Vargas said.
Casara's boyfriend, 16-year-old Dolton teen Anthony Lee and his brother 21-year-old Diante Coakley of Chicago were both charged with first-degree murder for the Christmas Day shooting of pregnant teen.
Lee is the father of Casara's baby.
"She was so beautiful," said Imani Henry, Eva's cousin. "We'll miss her a lot, it's really hard on the family."
In court, prosecutors said the attack was the result of a robbery gone bad.
Authorities say it happened after Lee, Coakley, their brother and Casara left the home of the brothers' grandmother and went to 152nd and Dorchester in the south suburb, where they planned to rob someone Casara arranged to meet.
Investigators say when that person drove up with a passenger, Casara and Coakley got into the car and had a conversation with the driver, who then told Coakley to get out.
Prosecutors say he did but then tried to open the driver's door and that's when the driver pulled away.
With Casara still in the back seat, Coakley and one of the other brothers allegedly opened fire on the car, unintentionally hitting Casara in the head.
"I don't believe at all that she knew what was going on," said Melody Vargas, Eva's aunt. "What him and his brothers did, it's a lot of speculations."
When the driver and his passenger realized she was still in the car and had been hit, they dumped her.
The 17-year-old was found between two homes in the 1100 block of East 152nd Street by a passerby.
She managed to stay alive long enough for her 1-pound, 5-ounce baby later named Lailani Paris Casara to be born.
Despite the arrests, police are seeking a third brother as a suspect.
"I ask you to turn yourself in. You know who you are, we know who you are," said community activist Andrew Holmes.
Authorities say the three brothers went back to their grandmother's home, and when they didn't find Casara, Lee and Coakley went to Gary, Indiana.
Outside the courtroom, the Dolton police chief did tell the family that investigators are hoping to arrest a third suspect in the next week.
