16-year old Chicago gangster on school property shoots at rival and unintentionally hits fellow student

A 16-year old boy was on school property, where he had been thrown out earlier in the day for making threates, when he spotted a rival gang member.  He then pulled out a loaded .22 handgun and fired, but missed the rival and instead head a female student in the wrist.

From an article:

Johnathon Calvillo, who prosecutors said was a gangmember, was told to leave North Grand High School earlier Wednesday after he threatened to fight another student, prosecutors said in court today in his bond hearing. He was ordered held on $1 million bail. 

But rather than staying away from the school where he is a sophomore, Calvillo returned to school at 3:00 p.m. to pick up his girlfriend, prosecutors said. 

At that point, Calvillo spotted a rival gangmember across the street from the school and pulled out a 22-caliber handgun and fired, prosecutors said. 

He was shooting from the 1700 block of North Kedvale to the 4100 block of West Wabansia Avenues, according to police and prosecutors. North Grand High School is at 4338 W. Wabansia Ave. 

But rather than hit the rival gang member, prosecutors say, Calvillo struck a 19-year-old female student who was walking to the Pulaski bus stop, prosecutors and police said. The woman was wearing headphones when she heard the gunshot and felt the pain in her arm. 

She was shot in the left wrist, police and prosecutors said. 

Prosecutors said police happened to be in the area and witnessed the shooting. Calvillo tried to flee but police were able to arrest him within minutes of the shooting, prosecutors said. A 22-caliber gun was found near where Calvillo was detained, prosecutors said. 

After being arrested, Calvillo admitted to being a gangmember and said one of his friends was killed earlier that day by a member of the same rival gang as the suspected target. 

Calvillo told police that he tried to shoot the rival gang member whom he identified as "Speedy" in retaliation. 

The woman was taken to Norweigian American Hospital where she was treated and released for a gunshot wound to her wrist.

The article didn't say where the boy got his gun and ammo.

Every gun in the hands of a child must first pass through the hands of an adult.
