CHICAGO — An 18-year-old woman was killed after another woman — reportedly a romantic rival — chased her in an SUV and rammed her into a Morgan Park tree repeatedly on Saturday night, police said.

An argument turned into a chase when a woman, 24, got into a car and chased the other woman on the sidewalk. The driver used her car to ram the victim into a tree and struck her repeatedly before fleeing the scene, police said.

The driver, identified as Chynna Stapleton, was later arrested by police and charged with murder.

The victim, Tatyanna Lewis, was found dead at the scene of the incident that occurred at 11:10 p.m. in the 11400 block of South May Street.

She is the daughter of a Chicago police officer, according to reports.

Wtinesses told ABC7 that the driver was upset by rumors she had seen on social media that the now-deceased woman was in a relationship with the father of the driver's child.

Activist Andrew Holmes told the Sun-Times that there was a child in the back seat of the SUV at the time of the incident.

One witness told the station that he had heard shouting.

"All I heard was, 'Get out of the way' and when I came out here she was driving up on her. She hit her with the car and, like, drug her into the tree," said the witness.

Another witness told CBS2 that the situation was "devastating," adding, "I've never seen anything like this before in my life."

The 24-year-old driver, of the 300 block of East 131st Place, hit another vehicle about a mile away and was arrested.
