Conviction Brings Permanent Sentence in Kenosha Homicide

A Wisconsin court has sentenced 43-year-old Justin Tercek to life imprisonment without the possibility of parole for the fatal stabbing of a recently relocated homeowner and his pet dog during a violent home invasion in Kenosha.

The sentence was handed down on July 17, bringing an end to a case that drew widespread attention after prosecutors revealed that the defendant had claimed he was “possessed by demons” before the deadly attack.

Fatal Attack Days After Home Purchase

Authorities said the victim, Andrew Pfannkuche, 52, had moved into his newly purchased residence only three days before the fatal incident on Feb. 3, 2025.

According to court records, Tercek unlawfully entered the property and confronted Pfannkuche, insisting that the house belonged to his grandmother and accusing the new homeowner of trespassing. During that initial encounter, Tercek allegedly removed a set of keys from the residence before leaving.

Investigators later determined that Tercek’s grandmother had previously owned the property. Following her death, the home was sold through her estate, and Pfannkuche became its lawful owner.

Suspect Returned Repeatedly Before Deadly Stabbing

Prosecutors said Tercek returned to the residence several times after the first confrontation. During one of those visits, he allegedly launched a fatal knife attack, killing both Pfannkuche and the victim’s dog, Jake.

The victims were discovered later that day after members of Tercek’s family visited the home intending to apologize for his earlier behavior. Instead, they found the tragic crime scene and notified authorities.

Jury Verdict and Criminal Convictions

Following a trial, a jury found Tercek guilty on April 21 of multiple felony charges, including:

• First-degree intentional homicide
• Mistreatment of an animal causing death
• Burglary
• Criminal damage to property

The convictions paved the way for the court to impose the maximum sentence under Wisconsin law.

Court Hears Troubling Details Before Sentencing

During sentencing proceedings, the court learned that Tercek had been released from jail shortly before the fatal attack.

Prosecutors also presented testimony indicating that Tercek had reportedly told a pastor one day before the killing that he believed he was possessed by demons.

Tercek chose not to make a statement before the court prior to receiving his life sentence.

Family Shares Emotional Victim Impact Statements

Several relatives and close friends of Andrew Pfannkuche addressed the court, describing the devastating impact of his death.

His niece, Antoinette Leon, said that no sentence could restore what the family had lost, explaining that they continue to miss his laughter, family gatherings, and the presence he brought to every holiday and celebration.
