CHICAGO – A Chicago judge is showing no mercy for three gang members allegedly responsible for a “heinous incident” at a local elementary school that left two young girls with bullet wounds.

Cook County Judge Peggy Chiampas lashed out at the oldest of the three suspects, Raekwon Hudson, as the 19-year-old stood before her bench in the Leighton Criminal Court Building in a torn green hoodie and black T-shirt for his arraignment on two counts of attempted murder Sunday, the Chicago Tribune reports.

“That young children in this city can’t participate at a picnic at the end of school without being in fear of their lives because of gangbangers in the street – juvenile gangbangers as well – have access to guns … no bail,” Chiampas said.

Police allege Hudson and two unnamed 17-year-olds participated in a drive by shooting at Pill Hill’s Warren Elementary School around 1:40 p.m. Friday that left two young girls with gunshot wounds.

The girls were among numerous students enjoying an end-of-school picnic when at least 11 rounds from a .40 caliber handgun were fired through the playground from a dark-colored Jeep.

Chicago Police Supt. Eddie Johnson told NBC Chicago the apparent targets of the shooting – former students – were blocked by school security from joining the picnic, and left the school and went to the corner of E. 92^nd and S. Chappel Ave., where they “loitered.” A short time later, the former students returned with the Jeep firing in their direction.

“The individuals being shot at then ran back into the picnic area drawing that fire to the folks that were in there enjoying the picnic,” Johnson said.

The girls – 7-year-old Jayla Wright and 13-year-old DaKayla Hart – were caught in the madness as they attempted to take cover.

Wright suffered a gunshot to the thigh and a graze wound to her right hand, while Hart took a bullet in her right hand, as well, prosecutors told the Tribune.

“She’s in a lot of pain,” Vaytonna Hart, the 13-year-old’s mother, told CBS Chicago Friday evening.

“Everything is starting to hit her now, and she’s ready to cry,” Kayla’s father, Emerson Hart, says of the girl’s experience. “But she’s going to be all right — she’s alive.”

Both girls were transported to Comer Children’s Hospital.

Prosecutors contend witnesses pointed to Hudson as the front-seat passenger in the vehicle, and alleged he flashed gang signs before the shooting. A surveillance camera in the area showed at least one person shooting out of the back seat of the Jeep and police recovered 11 shell casings in the street.

Police allegedly spotted the Jeep pulling into a garage on South Philips Street as the garage door was closing and arrested the three suspects as they attempted to flee out of another door. Hudson allegedly had the key fab for the Jeep when police caught up to him.

Hudson’s lawyer, meanwhile, alleged the 19-year-old was home at the time of the shooting and found two teens in his garage. The attorney told the court Hudson was wrestling with the teens when police arrived and made the arrest.

Hudson’s attorney contends his client is a high school graduate with plans to enlist in the U.S. Navy.

Police did not release the identities of the other suspects because they are juveniles, the Tribune reports.

All three suspects face two counts of attempted murder, two counts of aggravated battery with a firearm, and a misdemeanor trespassing charge.

Chicago Mayor Rahm Emanuel addressed the schoolyard violence during a visit with the victims’ families at the Comer Children’s Hospital on Friday.

“This is a parent’s worst nightmare,” a visibly angry Emanuel told reporters, according to CBS Chicago. “Those kids were out on the playground enjoying their childhood.”

“There is no person in Chicago who is not disgusted by this incident. These are our kids. They deserve their childhood uninterrupted by a bunch of gangbangers,” he continued. “I would hope for once, when people say enough is enough … that the justice system … understands what enough is enough is.”
