A Chicago man is charged with murder for stabbing a Walgreens employee to death on a fatal Labor Day weekend in the city, authorities said Tuesday.
Frank Williams, 18, attempted to rob the pharmacy in the Wicker Park neighborhood early Sunday before grabbing Olga Marie Calderon, 32, mother of two, by the neck while she was stocking shelves, police said.
Then he stabbed her several times when she tried to push him away.
“In this case, whatever set it off – whether it was a minor setback or whatever – was instantly transformed from a robbery that so quickly led to brutal murder,” said Police Cmdr. Eric Winstrom said.

Investigators checked the surveillance camera footage to track Williams back to the apartment complex he lives in, Winstrom said, adding that the suspect did not take anything from the store.
Detectives found a knife and clothes that Williams allegedly threw away in a nearby courtyard, the commandant added.
Williams allegedly committed two previous robberies last Wednesday, one in the same Walgreens store and one in a Walgreens store in a different neighborhood, authorities said.
The suspect has been charged with first degree murder and has scheduled a trial Wednesday. It was not immediately known whether he had legal representation.
It was not immediately known if the suspect and Calderon had any prior interactions, authorities said.
“This is an incredibly tragic incident,” Chicao Police Chief Brendan Deenihan said Tuesday, according to the Chicago Sun-Times. “Just being with a Walgreens, working for your family and getting someone, a perpetrator, to do a heinous act like this and stab the victim.”
The bloody crime took place over a violent Labor Day weekend in the city that resulted in 10 murders, 38 shootings, and 51 shooting victims between 6:00 p.m. Friday and 11:59 p.m. Monday, a Chicago police spokesman told Fox News.
