CHICAGO — In the first homicide to hit South Chicago Heights since 2009, a 14-year-old student is now in police custody, accused of killing his 16-year-old brother.

Investigators have been pulling evidence out of the brothers’ home all day, located at 187 West 29th Street.

Police say they were initially called in at around 7 a.m. about a stabbing.

When they arrived, the brothers’ sister was CPR on her 16-year-old brother.

Police said the 16-year-old had been stabbed in the back by his 14-year-old brother with a kitchen knife.

Also a witness to this was the mother of the children. Police say four children live in the home: three teenage boys and a girl.

Neighbors recall a number of times police have been called to this home, in the short time they’ve lived here.

The teens were getting ready for school, as everything went south.

“The two juvenile brothers were engaged in an altercation in the basement apartment, and their mother came and started to interfere and started to break up the argument and then the one brother, the alleged offender, picked up a knife and stabbed his older brother we believe one time in the back. The mid section of the back,” said South Chicago Heights police chief Bill Joyce.

Abel Tovar, a neighbor, said, “I do know there was some domestic problems there in the past. Police have been called maybe four or five times, you know, within the six months they’ve lived there.”

No charges have come down yet against the 14-year-old, and WGN is told there’s a possibility he could be charged as an adult.

The police chief said the 14-year-old did run away from the scene after the stabbing, but was brought back by his grandfather, who lives nearby.
