Naperville Man Charged in Fatal Shooting at Lincoln Square McDonald's View Full Caption

CHICAGO — A Naperville man planned to rip off the drug dealers he met in a Lincoln Square McDonald's parking lot Monday, and ended up killing one of them, prosecutors said Friday.

Cordero Sims went to the fast-food restaurant in the 4900 block of North Lincoln Avenue Monday night to buy a pound of marijuana, prosectuors said. Sims, 26, and two other people agreed to pay $4,500 for the drugs, Assistant State's Attorney Maura White said.

But the trio decided to stiff the sellers by stuffing a stack of 462 dollar bills in a plastic bag "in an effort to trick the victims," she said.

Sims and his friends rode to the McDonalds in a dark colored SUV and parked alongside the BMW driven by the sellers, White said. With the money in hand, Sims got into the victims' car. He handed over the sack of money and asked to inspect the drugs.

Sims "wanted to see that the product was an entire pound of cannabis because he didn't want to be shorted," White said.

When one of the men went for the bag of money to make sure it was all there, Sims pulled a gun, White said.

A struggle followed, and Sims shot 24-year-old Irbinzon Gonzalez three times in the back of the head.

The other man begged with Sims not to kill him and ran from the BMW, White said.

White said a witness, who has two children with the man, was watching the ordeal from Sims' SUV. She then chased after Sims, striking him several times to prevent him from shooting the man.

Sims allegedly gave up the chase and jumped back into the SUV, fleeing down Western.

Gonzalez, of the 2600 block of West Winnemac Avenue, was found dead in the front seat of the BMW.

Sims was convicted of a felony gun charge in 2010, and sentenced to six years in prison. He served time in Cook County Jail in 2008 for aggravated assault. In 2006, he served two stints at boot camp for selling drugs and illegal gun possession.

Sims was ordered held without bail in bond court Friday.
