Police have taken into custody a person of interest after the fatal stabbing of a woman on a Chicago Transit Authority Red Line train on the South Side, WLS reports.
The still-unidentified woman was stabbed in the neck around 12:30 p.m. Thursday and was pronounced dead at the scene.
Passengers who witnessed the gruesome attack said that a man asked the woman, who was sitting across from him, a question about having children.
"He asked the young lady a question, she said no, and he got up and started stabbing her," Andrea Patterson, a witness, told the station. "She fell toward the floor and he slit her neck."
Some witnesses tried to help the young woman, but because the man still had a knife, they were hesitant to try to subdue him. The man eventually ran off the train and onto the platform, where, authorities say, he was apprehended by police.
First Deputy Police Superintendent John Escalante described the incident as "domestic in nature," saying that the victim and the suspect apparently knew each other.
Chicago Police Superintendent Eddie Johnson echoed Escalante's words, hoping to quell safety concerns.
"It is still an ongoing investigation, but what I can tell you is that it appears to be domestic in nature, and so the general public was in no harm at the time," Johnson said.
Police noted that CTA has multiple security cameras on the train and platform, which they are hoping will help with the investigation.
