CHICAGO (CBS) — A parolee from the city’s West Side is charged with shooting and wounding to Chicago Police officers as they investigated a drug deal earlier this week.

Daniel Jones, 27, of the 600 block of North Ridgeway Avenue, is charged with two counts of attempted murder in the shooting of the two officers, both 29, on Monday evening. Jones was also wanted on an unrelated warrant.

Cook County Judge Ramon Ocasio III ordered Jones to be held without bail at a bond hearing on Thursday.

An attempted drug stop was in progress when the suspect opened fire on police and injured the two Harrison District officers.

The officers, who had both been on the job for three to four years, were on patrol at Karlov Avenue near Wilcox Street – between Monroe and Adams streets – when they saw a drug deal going down in an alley around 10:45 p.m. Monday

As they got closer, police say one man pulled out a gun and opened fire on them.

“A number of shots were fired where both officers were struck. One was grazed in the left head and in the left bicep,” police Supt. Garry McCarthy said soon after the shooting. That officer was treated and released from the hospital.

“The second officer was hit square behind his left ear and the bullet is lodged. It’s a very serious wound,” said McCarthy.
