Chicago Police Krysztof Marek is accused of killing five of his neighbors in Chicago.

Krysztof Marek is accused of fatally shooting five of his neighbors in a rampage at a Chicago condominium complex on Saturday, October 12. Prosecutors say the 66-year-old retired construction worker and truck driver planned out the brutal attack and left behind notes in his condo meant to encourage himself to carry out the mass shooting, the Chicago Sun-Times reports.

Marek was arrested after the shooting, telling the officers he surrendered to, “I think you’re looking for me. I did it,” the Sun-Times reports. Chicago Police said spokesman Anthony Guglielmi said on Twitter that the incident stemmed from an ongoing dispute between Marek and his neighbors in the Northwest Side condo complex. Guglielmi called the murders in the city’s Dunning neighborhood, “devastating” and said Marek is accused of “nothing short of savagery.”

Authorities say Marek killed the married couple who lived in the condo, Tsvetanka Kostadinova and her husband, Ivaylo Popov, both 43, and their visitors, David Hanik, 61, and his girlfriend, Iskra Pourel-Popova, 65, who was Popov’s mother. Marek also shot and killed 53-year-old Jolanta Topolska, who lived in the apartment above Popov and Kostadinova, according to prosecutors.

1. Marek Shot & Killed 4 of the Victims While They Sat Down for Dinner at Their Kitchen Table & Then Gunned Down the 5th Victim After She Came Outside to See What Was Going On, Police Say

Chicago Police say the first four victims were sitting down for dinner in their condo in the 6700 block of West Irving Park about 5:30 p.m. when Krysztof Marek entered the apartment with a .40 caliber handgun and began shooting. He killed the two women and two men who were inside.

“All four bodies dropped to the floor around the table,” Cook County Assistant State’s Attorney James Murphy said in court, according to WGN-TV. “Victim 1, victim 2, victim 3 and victim 4, all sat around a set dinner table, with food on the table untouched.”

Marek then left the condo and shot the fifth victim. She had come out of her condo to see what was going on. Police say he shot her in the abdomen and then followed her as she tried to escape. He shot her in the back of the head, police said.

Two GoFundMe campaigns have been started to help the victims’ families. The GoFundMe for Jolanta Topolska says, “We will not be able to return Jola’s life, but we can show solidarity in these difficult moments for her family. We ask you to support Jola’s family who lost her in such a cruel way. The collected funds will be used to organize the funeral and send the ashes to Poland.”

The other four victims are Bulgarian. The couple who own the condo have children who lost their parents and grandparents in the shooting. The GoFundMe, organized to help them, says, “Dear friends, with a heavy heart, we share our pain for our tragic loss of our Mother, Father, Grandma, and Grandpa. They were ripped away from us in one single moment the evening of October 12th, 2019 in Chicago.”

“The unsuspecting Tzveti, Ivo, Iskra, and David were sitting together for a family dinner at their home, without knowing that this would be their last meal on this world. They were killed brutally, shot, without any mercy by an individual who was psychologically disturbed,” the GoFundMe adds. “We are asking for financial help, because this quadruple tragedy is impossible for us to handle at this moment, on our own. Please help us with the funeral expenses. Thank you in advance from the bottom of our hearts for any amount of money you are able to donate, no matter how big or small! God bless you.
