Cook County jury has convicted a 22-year-old reputed gang member of killing a Chicago police officer two years ago.

 

Shawn Gaston, 22, was convicted of first-degree murder in the death of Officer Alejandro “Alex” Valadez on June 1, 2009.

Jurors reached their verdict late Wednesday evening, just a few hours after beginning their deliberations, following a weeklong trial.

Valadez was 27 years old when he was shot to death in 2009. He had been on the force for only three years and was working undercover duty on the South Side on June 1, 2009, investigating reports of gunfire when Gaston allegedly gunned him down on the 6000 block of South Hermitage Avenue
