Man killed and wife wounded while celebrating Puerto Rican Day Parade in Chicago

Gyovanny Arzuaga and Yasmin Perez were shot on West Division Street on the Northwest Side around 9:15 p.m. Saturday, hours after the parade had ended. Police said they were ambushed by three men. A Facebook video that was allegedly of the shooting showed the victims being pulled out or falling out of a car with a Puerto Rican flag.

Chicago police are still investigating how a 4-year-old boy and 17-year-old were shot on Monday, and a 15-year-old might hold the answer.

The two victims were shot in an apartment on South Ellis on Woodlawn. As officers arrived, they noticed a 15-year-old boy crossing the street holding his side. He admitted that he had been upstairs, police said, and told officers they better go check on the people inside. 

Officers patted the 15-year-old down and said they found a gun. It's not clear if this was the gun that shot the child and teenager.

The 15-year-old is expected in juvenile court on Tuesday.

The child and teenager were both hospitalized in good condition.
