WICKER PARK — Police are questioning a person of interest in the killing of Olga Maria Calderon, a 32-year-old mother who was fatally stabbed Sunday while working at a Walgreens in Wicker Park.
Charges are expected Tuesday, Chief of Detectives Brendan Deenihan said during a news conference.
Police did not provide any additional information about the suspect or a potential motive in the slaying.
At 9:36 a.m. Sunday, Calderon was working inside the Walgreens, 1372 N. Milwaukee Ave., when someone came into the store, walked up to her and stabbed her multiple times, police said.
Calderon, 32, was pronounced dead at the scene. The attacker ran off and didn’t take anything from the store, police said.
Calderon’s death was ruled a homicide by the Cook County Medical Examiner’s Office. She lived in Humboldt Park, according to the office.
A GoFundMe campaign created by Calderon’s sister, Andrea Calderon, has raised more than $28,000 as of Tuesday morning. GoFundMe proceeds 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.
