Krysztof Marek Charged With Murder In Deaths Of 5 In Dunning Neighborhood

CHICAGO (CBS) -- A North Side man has been charged in the deaths of five people shot dead in the Northwest Side's Dunning neighborhood over the weekend.

Krysztof Marek, 66, was charged with five felony counts of first degree murder, according to the Chicago Police Department.

A Cook County judge ordered Marek held without bail on Monday, calling the killings "evil on steroids."

Marek was arrested Oct. 12 shortly after 5:30 p.m. and is charged with the murders of a 61-year-old man, a 65-year-old man, a 53-year-old woman, a 30 to 35-year-old woman and a 40 to 45-year-old man in the 6700 block of West Irving Park Road, police said.

According to a tweet from CPD, the incident was the result of a dispute between Marek and his neighbors.

Investigators said Marek, who lived in the building for about 15 years, exited his own condo and walked into a neighbor's condo. He shot four people who were seated at a table eating dinner there, killing them all, police said.

He then went upstairs to the third floor, entered another condo, and shot a woman there, police said. That woman was first taken to the hospital in critical condition, according to police officials, but she died late Saturday.

The Cook County Medical Examiner's office has identified two of the five victims. One is identified as Tsvetanka Kostadinova, age unknown, and another is identified as Jolanta Topolska, 53.

Kostadinova was killed by a gunshot wound to the chest, as were two other victims, the Medical Examiner's office said. Another victim died of multiple gunshot wounds, and another died of a gunshot wound to the abdomen, according to the Medical Examiner's office.

While the Medical Examiner's office had not released the names of the other three victims, crosses set up in front of the condo building identified two of them as Danail Mladenov and Ivaylo Popov.

Investigators recovered the shooter's handgun and are looking into how he got it.

In 2017, Marek filed for bankruptcy, and DLJ Mortgage Capital, Inc., filed foreclosure against him at his condo. The foreclosure lawsuit is still pending.

The building manager at the condo complex told CBS 2's Chris Tye that Marek "flipped out" when the condo association voted him out as the condo board president, around the same time he filed for bankruptcy. Although neighbors expected him to do something "stupid" at the time, they did not expect something like this.
