Court Released Suspect, Ignored Ankle Monitor Violations Before He Murdered Woman

Melrose Park, IL – A suspect charged with stabbing a Walgreen’s clerk to death was already facing charges for stealing 14 pistols from a Melrose Park gun shop and shouldn’t have been on the street.

The owner of Suburban Sporting Goods Guns & Ammo said that then 17-year-old Sincere Williams was caught on video smashing the front glass of his store with a hammer at least 20 times in early May, WBBM reported.

The owner said that Williams grabbed 14 handguns and tried to flee but was quickly arrested.

“That’s a pretty heinous crime,” the owner said. “These weren’t hunting guns. He wasn’t stealing to feed his family. These were likely going somewhere very bad.”

But Williams was two months shy of turning 18 so prosecutors charged him as a juvenile, WBBM reported.

The gun store owner said he was furious.

“I was kind of enraged. It’s like, here’s this kid that broke into a gun store and stole several firearms,” the owner said. “Just because he was caught, it doesn’t lessen the severity of the crime.”

Then in August, Williams’ victim – the gun shop owner – was notified that the alleged thief had violated the conditions of his release, WBBM reported.

But despite the fact that Williams had illegally removed his electronic monitoring device while the charges were pending, the court ordered that his monitoring bracelet could be removed, and the Cook County prosecutor voiced no objection.

The burglary charges against him remained pending.

A few days later, the now 18-year-old Williams brutally attacked 32-year-old Olga Marie Calderon as she worked at a Walgreens in the 1300-block of N. Milwaukee Avenue in Wicker Park, WBBM reported.

Williams fled and left Calderon to die after stabbing her at least 10 times, WBBM reported.

“The Defendant then turns around and leaves the Victim on the ground. The Defendant then calmly walks out of the Walgreens with the knife and calmly walks through the parking lot southwest out of view,” according to court documents.

Court documents also showed that Williams had prepared to commit the murder and brought a change of clothing with him, WBBM reported.

Prosecutors said a series of police and home security cameras captured video of Williams as he made his way from the scene of the murder to his apartment in Old Town.

Video showed Williams changed his clothes after the murder and tossed a bloody shirt into the bushes of a nearby house, WBBM reported.

But the videos showed he had bloodstains on his pants and was wearing the same shoes.

“You can clearly see the Defendant’s face and the blood stain on his pants,” according to the complaint.

Police found two knives, one of which was believed to be the murder weapon, WBBM reported.

Prosecutors said they also recovered bloody gloves with a cut in them.

Williams’ mother told police that her son said he had cut his hand on a fence and so she took him to the hospital for stitches after the murder, WBBM reported.

Court documents said that a search warrant was executed on Williams’ home and turned up the shoes he had worn to stab Calderon and the packaging for the knife found near Walgreens.

Police said Williams is a suspect in the robbery four days earlier of the same Walgreens where he later murdered the clerk, WBBM reported.

Officials said he is also a suspect in the robbery of a Walgreens located near North and Western Avenues.

The owner of the gun shop that Williams robbed said he believed Calderon’s death could have easily been avoided, WBBM reported.

“It enraged me that a woman is now dead and all they had to do was keep this guy in custody,” the gun shop owner said. “Obviously, it could have been prevented. He was in custody in May. I’m appalled that’s how our system works.”

Police did not initially reveal that Williams had been arrested for stealing guns in May when reporters asked about the alleged killer’s criminal record, WBBM reported.

“Sincere Williams turned 18 on July 4th,” Chicago Police Area Five Commander Eric Winstrom explained. “In a very limited time, we believe he committed three robberies, but as far as interaction with the Police Department that was documented, there is none.”

The public defender representing Williams said his client has schizophrenia, WBBM reported.

A judge denied bail to Calderon’s alleged killer on Sept. 9.
