CHICAGO (CBS) – A 14-year-old boy is dead, after being shot accidentally by a sibling at his Far South Side home.

As CBS 2’s Dana Kozlov reports, the family of Jalil Muhammad, 14, spent most of the morning at the Calumet Area Police Headquarters, 727 E. 111th St. Ultimately, police said Muhammad had been shot by his 10-year-old brother who fired a gun accidentally.

Authorities have charged the victim’s father, Lyle Muhammad, 44, with not having a Firearm Owner’s Identification Card and failing to register a firearm. Both are misdemeanor charges, for which he is due in court Dec. 13.

On Tuesday night, Jalil Muhammad’s family thought he was having a seizure when he collapsed at the table. But it turned out he had been shot.

Paramedics responded around 7:20 p.m. to the family’s home in the 200 block of West 93rd Place, Fire Media Affairs Director Larry Langford said. Paramedics initially thought he had fallen and hit his head. They discovered the bullet wound later behind the boy’s ear.

An ambulance took Jalil Muhammad to University of Chicago Comer’s Children’s Hospital, Langford said. Muhammad was pronounced dead at the hospital at 8:05 p.m., according to the Cook County Medical Examiner’s office spokeswoman.

A doctor at the hospital found the bullet wound, alerting police to go to the home, Morado said.

On Wednesday morning, police were still guarding the family’s home, and red crime scene tape kept people from knocking on the door. Neighbors were confused about what happened.

“I didn’t hear anything. I was sitting in my window at the computer, and we just saw the ambulance pull up,” said neighbor Tasha Grady.

Grady called Jalil Muhammad a wonderful young man from a close, protective family.

“Very loving, very caring, Anytime he would see me come out to my car, he’d say, ‘Hi, Tasha!’ and he’d run up and give me a hug,” she said.

“I had to tell my girls this morning what happened. And it just tore them up. Everybody knew this kid and just loved him. He was just such a bright and wonderful child,” said Grady.

When neighbor Daisy Blocker was told Jalil’s 10-year-old brother accidentally fired the fatal shot, she said, “It’s very hard. I just couldn’t believe it because the kids were very close.”

Everyone who knows the Muhammads describes them as a wonderful family. But it’s a family now torn apart by a bullet.

“I know they’re devastated, I know they are,” said Grady. “They were both just wonderful parents, very protective of the children.”

Grady said a short time after the ambulance left the 93rd Street cul-de-sac, it was swarmed with police cars and there was even a police helicopter overhead.

Muhammad’s parents and his younger brother are believed to have been home at the time of the incident.
