Brazen 'squatters' have moved into a San Francisco home that is owned by a man who was murdered last summer, according to his family's attorney. 

Przemyslaw Jeziorski, 43, was shot and killed by a masked shooter July 4, 2025, in Athens, Greece.

Jeziorski, a UC Berkeley professor, was executed in broad daylight in connection to a custody dispute with his ex-wife Konstantina Nadia Michelidaki, who was described as the 'mastermind' behind the murder by the victim's family. 

Christos Dounias, Michelidaki's then-boyfriend, confessed to being the shooter just days after Jeziorski died. The two of them and three others were arrested for allegedly plotting to kill the educator. 

Michelidaki was found dead in her prison cell in Greece in an apparent suicide on June 4, leaving their two twin children orphaned and in custody of Łukasz Jeziorski, the victim's brother, according to Erin Stratte, the lawyer representing Jeziorski’s family. 

Michelidaki vehemently denied being involved in her ex's murder and had only been charged with his death. 

Jeziorski, who also went by PJ, owned 'multiple properties and businesses' with Michelidaki before he died, including a location on Marin Avenue in Berkley that they rented out as an Airbnb, Stratte said. 

After his brother was killed, Łukasz inspected the home and found it 'in order', but on December 4, 2025, neighbors called police over a suspected robbery at the 2,167 square ft property.

The unidentified squatters are believed to have gained entry to the home around 2.30am by kicking in the front door, Byron White with the Berkley Police Department (BPD) told SFGATE. 

The four masked suspects fled the scene before cops arrived, and officers failed to stop them in their vehicles while attempting to pull them over, White stated. 

But later that morning, a woman who is believed to be one of the alleged squatters, showed up at the home and claimed to police that she was renting a room from the landlord, according to White. 

The unnamed woman said she was out of town when the home was broke into and that she attempted to phone the 'landlord,' but the call 'wasn't going through,' she told police, per the report. 

'I didn’t think anything of it because when I met her and we did walk through she told me how she travels a lot and always isn’t in [the] Bay Area,' the woman wrote in her statement.

She claims to have moved into the home on October 1 after touring it in August with someone she believed to be the homeowner. The alleged tenant said she paid $30,000 for a one year lease, along with a $500 deposit, SFGATE reported.

According to Stratte, the alleged squatters went on to report their own robbery as a way to 'to establish their occupancy,' and are now protected by tenant laws 'even though they gained entry criminally'. 

Jeziorski's family first uncovered suspicious activity at the home in January when someone found 'evidence that people had been there,' Stratte told the outlet. 

They went on to notify the Alameda County Sheriff’s Office, sparking the start to the legal process to remove them.

An 'individual representing the homeowners' contacted the BPD on January 29 about suspected squatters, and officers located a man and woman in the home who said they were renting it out, White told the publication. 

Investigators decided the dispute would have to be resolved in civil court. Eviction notices were filed against the woman and another dweller on April 21, SFGATE reported.

But Stratte said a 'loophole in California law' has made it hard to remove them. 

According to the family attorney, the alleged squatters 'claim to have a contract for rent drafted with PJ’s murderer who was in custody in a prison in Athens Greece at the time of the alleged lease date,' referring to Michelidaki. 

'Even though it is a clear impossibility, the Court will not presently act to evict and the police currently refuse to remove them under color of a California law that needs to be changed,' she added.

Stratte continued: 'Nadia could not have entered a lease with these criminal squatters as she had no access to computers or English-speaking agents that would enable  her to complete such a contract.' 

One of the suspected squatters was arrested for other crimes on the same day they were found, according to the lawyer. 

Neighbors have also reported people stealing items from the home, which Stratte said is 'taking advantage of orphan children that have a right to this property'. 

Jeziorski was shot five times in a suburb of Athens near his ex-wife's house. He was visiting the country to visit his two children and attend a family custody hearing. 

More than a week after losing his brother, Łukasz and his family, who have had an 'impossible' time accepting his death, said he was a loving family man. 

'He cared about his family. He fought for them until the end,' Łukasz previously told the Daily Mail of his brother, a highly-decorated educator.

'He wanted to bring his children to his hometown of Gdynia, Poland, as he did every year. He planned a trip to Disneyland in Paris. He was very family-oriented and friendly,' Łukasz added.
