CHICAGO (STMW) — After allegedly stabbing his sister’s German Shepherd to death and trying to clean up the evidence Wednesday, Chicago Police said a Portage Park man locked the door to his home and waited with a knife in his hand for his brother-in-law to come in.

“I felt as if it would be an epic battle,” Andres F. Duran allegedly told police. “Like fighting Satan.”

Instead, prosecutors have now charged Duran, 29, with aggravated cruelty to animals and animal torture for stabbing the 4-year-old male German Shepherd, named “Diesel,” to death at Duran’s home in the 4300 block of North Mobile.

Cook County Judge Adam Bourgeois Jr. ordered Duran held in lieu of $150,000 bail Sunday.

Duran turned himself in to the Animal Crimes Team at Homan Square, according to police reports. When he was arrested he was carrying a Taft High School ID, a jury summons, miscellaneous writings and a “black case containing throwing stars,” records show.

Assistant State’s Attorney Anthony Lucafo told Bourgeois that Duran became “enraged” — and Duran allegedly told police he “lost control” — before stabbing the dog in its side in the front bedroom of the house.

The dog didn’t die fast enough, Duran allegedly said, so he stabbed it in the neck. Duran also said the dog bit his right arm.

Lucafo told the judge Duran wrapped the dog’s body in a blanket, put the blanket in a suitcase and put the suitcase in the back yard. Police reports show the suitcase was found near the garage.

Duran told police he wanted to get rid of the evidence and began to clean up the blood. That’s when he said he heard his brother-in-law at the back of the house, so he locked the door.

“I was waiting for him to get in with my knife in my hand,” Duran said.

But police reports show Duran eventually fled and got rid of his knife and bloody clothes. Lucafo said Duran’s sister found the dog in the backyard.
