CHICAGO (CBS) — Police have issued a warrant for the arrest of a man wanted for his involvement in a shooting last week in Avondale Park, which wounded two small girls.

Dionisio Gonzalez, 31, whose last known address was in the 3000 block of West Belden Avenue, is wanted in the warrant on charges of aggravated battery with a handgun.

He is being sought in the June 8 shooting that wounded Jocelyn Rodriguez, 7, and a 2-year-old girl, in the park in the 3500 block of West School Street.

Another suspect, Antonio Bucio, 22, of the 6200 block of South Tripp Avenue, has already been charged with two felony counts of aggravated battery with a firearm and unlawful use of a weapon in a shooting in connection to the shooting. He is being held without bond.

Prosecutors said Bucio is a member of the Maniac Latin Disciples street gang, and he was angry on the evening of the shooting that he had been “disrespected” by members of the rival Latin Kings.

Bucio was riding in a van with two other men and two women around 7:45 p.m. that night, when he jumped out at the park and exchanged gang signs with some Latin Kings playing basketball, prosecutors said.

Then Bucio allegedly opened fire, wounding the two little girls as they played in the sandbox.

The 2-year-old girl was grazed in the head, while Jocelyn remained in critical condition at last report, with a bullet wound to the back.

At the very same time as Bucio was allegedly firing into the park, a community policing meeting was underway steps away in the park’s field house. A police officer, and Ald. Ariel Reboyras (30th) were among those present.
Neighbors said the Chicago Alternative Policing Strategy (CAPS) meeting abruptly came to an end when the shots rang out, and everyone was instructed to hit the floor.

Soon afterward, neighbor JoAnn Trainer was escorting children into the field house from the playground as they wept in horror.

Later, police found the van in which Bucio was allegedly riding abandoned about two miles away in Logan Square, and recovered a .45-caliber handgun from the vehicle.

Later, Belmont District officers saw a group of men and women running near the location of the abandoned van and stopped them for questioning. The officers took down their names and other identification, then let them go. The “contact cards” the officers filled out became crucial in identifying Bucio as the shooter, a police source said.

Police have not revealed the alleged role that Gonzalez had in the incident.
