Chicago police say four boys have been wounded in a shooting on the city's West Side.

Police spokesman Veejay Zala says the shooting happened just before 9 p.m. Monday when an unknown male approached and opened fire into a crowd.

Zala says a 14-year-old, 15-year-old, 16-year-old and 11-year-old were wounded. They were taken to hospitals, all in stable condition.

An investigation is ongoing.

A separate shooting on the South Side left one person dead and another injured.

Zala says two men were riding in a car when an unknown person or people opened fire. A 38-year-old was taken to a hospital in critical condition and a 39-year-old was taken to a hospital in grave condition and later pronounced dead.

The Chicago Tribune and Sun-Times report at least 14 people were wounded in shootings Monday.
