WICKER PARK — The Walgreens in Wicker Park where employee Olga Calderon was killed Sunday has reopened with boosted security.
Walgreens spokesman Phil Caruso confirmed a guard has been posted at the store, 1372 N. Milwaukee Ave., but he said he could not elaborate for security reasons.
“We are grateful to Chicago Police and law enforcement for their efforts and will continue to work with authorities,” Caruso said. “The safety of our customers and team members is our top priority. We are continually evaluating our security measures in all our stores. The store is has reopened with additional security measures.”
On Wednesday, mourners and well-wishers left flowers, balloons and candles near the store.
“We grieve for Olga’s loss from our community,” Ald. Daniel La Spata (1st) said. “I feel shock and frustration and anger and sadness any time someone loses their life to a violent crime in our ward.”
Calderon, a 32-year-old Humboldt Park mother, was killed Sunday while stocking shelves at the store.
Chicago police and Cook County prosecutors said Sincere Williams, 18, entered the store at 9:36 a.m. and stabbed Calderon multiple times.
Detectives believe Williams attempted to rob the store and that he was also responsible for other robberies that occurred days earlier. Williams was arrested Tuesday and denied bail Wednesday.

A GoFundMe campaign created by Calderon’s sister, Andrea Calderon, had raised $63,000 as of Thursday morning.
The money raised will go toward Calderon’s funeral expenses and to support her husband, Israel, and her two children, an 11-year-old daughter and a 3-year-old son.
Andrea Calderon wrote that her sister was “the world’s very best mom, a loving partner, a dedicated daughter, my big sister and so much more.”
“Her entire existence revolved around her little family,” Andrea Calderon wrote.
Chief of Detectives Brendan Deenihan said detectives solved the case without any eyewitnesses, relying on camera footage and other technology and using a bloodhound to track Williams.
La Spata credited the 14th District officers for their swift action in tracking down Williams.
He encouraged residents and business owners to send private camera footage to the 14th District’s CAPS office any time they believe the footage could be relevant to a crime.
“A lot of the 14th District [crime] is down significantly,” he said. “I want to make sure credit is given where credit is due.”
