Man shot on I-290 expressway on West Side

CHICAGO (WLS) -- A 19-year-old man was injured after an early Sunday shooting on the outbound Eisenhower Expressway on the city's Near West Side, officials said.

The shooting may have been retaliatory, Illinois State Police said.

No arrests have been made.

Police said a shooter opened fire on a car heading westbound around 2 a.m. near Racine Avenue, hitting a passenger in the leg. The driver transported that victim to a local hospital.

"He's OK, thank God he is," said Tamkia Loyd, who knows the victim. "But the violence needs to stop. Don't anyone care about each other's lives?"

Westbound I-290 lanes were closed as police searched for shell casings in the area, but re-opened around 5 a.m.

This is the seventh expressway shooting this year for Chicago. The city saw 40 shootings on area expressways in 2015 alone with the Dan Ryan Expressway topping the list. In 2014, there were 19 shootings.

Law enforcement officials said that most of the shootings are gang conflicts that spill onto roadways.
