The second victim was seriously wounded, although the extent of those injuries has not been released. Police say a suspect is in custody. No one has been identified.
Witnesses said the stabbing took place around 7:30 a.m. outside Infinity School, located in the 10200-block of South Crandon, as students were preparing to go through the security checkpoint to enter the building.
Charmayne Prince shares both her anger and pain just hours after her teenage son was stabbed to death, allegedly by another student.
"I'm not feeling anything," Prince said. "I don't know what to feel or how to feel.
"I got a call not even ten seconds after I heard on the radio, and it was from my brother's fiancé and she said, 'Chris passed away. He didn't make it.'"
Another classmate was seriously wounded while trying to break up the altercation that happened at the far South Side alternative high school that 17-year-old Chris Wormely attended.
Investigators say Chris Wormely was the intended target of the incident which happened around 7:30 Thursday morning.
The incident occurred as students were coming off a school bus but before they entered the school, where they are required to go through security screenings using metal-detecting wands and pat downs.
"They line up and it just started, they got into an altercation about something that happened yesterday. I can't tell what happened, though," said teacher Gail Cousins.
The school is run by AMIkids, an alternative therapeutic school that contracts with the Chicago Board of Education.
A spokesperson for the Tampa, Fla. based private company that runs the school says Wormely and his attacker had had some previous tensions and did receive counseling at school for some of the issues they were having.
"These particular students had tension and friction between them previously but never any kind of physical altercation previous to this incident," said AMIkids Director of Communications Sherri Ulleg.
Chris Wormely, who is learning disabled, attended the school where 20 CPS and non-CPS students ranging in age from 14 to 18 were educated. They all had been expelled or suspended long-term from Chicago Public Schools.
Chris is being remembered for his love of basketball and videogames as his family struggles with their loss.
"This shouldn't have happened to him because he don't mess with nobody," Prince said.
Officers are still searching for the weapon used in the attack. The school was closed for the day. Administrators plan to reopen the school on Friday with grief counselors on hand.
