Murder suspect charged in young woman's stabbing at Walgreens in Wicker Park


Sincere Williams charged in Milwaukee Ave. murder

Sincere Williams of the 1400 block of N. Sedgwick has been charged with one felony count of Murder-First Degree at 12:15 p.m. today, in the fatal stabbing of Olga Maria Calderon at Walgreens, 1372 N. Milwaukee Ave., in Wicker Park, during the morning of Sun., Sept. 6. 

Williams who turned 18-years-old on July 4 appears to have no record of prior crimes, though he is believed to be the person who robbed the Milwaukee and North Avenues Walgreens stores early morning on Sept. 2. 

When he appeared at the Milwaukee Ave. location on Sunday, his intent was apparently to once again rob the drug store with a knife. 


Commander Eric Winstrom, Area Five Detectives

"He approached the victim who was just stocking shelves," explained Area Five Detectives' Commander Eric Winstrom. "He grabbed her around the neck. It appears that she tried to push away and then he stabbed her multiple times, causing her death. 

"After the murder, Williams discarded the knife and clothing in a nearby yard, which the detectives recovered. Detectives spent hours and hours in our area technology center reviewing private and City surveillance cameras." 

That was how the police discovered where Williams went and they were able to identify him. It was his home in 1400 block of N. Sedgwick. Tactical officers from the 18th District assisted in the arrest. 

Winstrom confirmed that the description in the Sept. 2 robberies, including the knife, mask and description, matched Williams appearance on Sunday. The investigation of the two robberies continues. 


Chief of Detectives Brendan Deenihan

As Chicago Police Department's Chief of Detectives Brendan Deenihan said in a press conference about this crime, "A young lady going to work, doing everything she is supposed to do, trying to raise a family…this is an unbelievably tragic heinous act." Then he asked that everyone keep the Calderon family in their thoughts and prayers.

Denniihan thanked Area Five Detectives, the Cook County Sheriff's Department who loaned their blood hound to help track the offender as well as the officers assigned to the technology room. Technology was of particular assistance as there were no eye witnesses to the crime. The final part of bringing the case to this stage was working with the District Attorney's office. 

Winstrom gave an addition thanks to the 18th District and community members for their help.
