Updated story

A Naperville man has been charged in Monday's fatal shooting in the North Side Chicago neighborhood of Lincoln Square where a man was found shot in the head in a McDonald's parking lot.

Cordero Sims, 26, was charged with first-degree murder -- the neighborhood's first gunshot homicide in more than six -- and is due in court Friday, DNAinfo Chicago reports. Sims is accused of killing Chicago man Irbinzon Gonzalez, 26, in what police sources believe could have been a drug deal gone wrong.

Police say the 25-year-old man was found dead with a gunshot wound to the head in a dark blue BMW just after 7 p.m. in the 4900 block of North Lincoln Avenue, DNAinfo reports. The man was reportedly sitting in the car when one shooter or possibly multiple gunmen opened fire.

Sources say the shooter fled in a tan Nissan after the incident.

One Lincoln Square resident said he walked by the parking lot just before 7 p.m. and saw a man who looked to be in his 20s and a woman arguing. The man described the pair as “freaking out,” according to the Sun-Times, and said the two were in the restaurant by the time he walked along.

Police sources say the victim had possible gang ties and a felony record. According to WGN, the victim was seen arguing with another man inside the restaurant.

Three more people were shot overnight Monday, the Tribune reports, though the Lincoln Square shooting was the lone homicide.

According to RedEye crime reporter Tracy Swartz, Monday's homicide is only the second of the year in the well-to-do Northwest Side neighborhood and the first gunshot homicide in more than six years.
