A jury trial this week for a New Jersey man who threatened the Bloomfield Township treasurer ended on its second day with a guilty verdict.

Marc Aisen, 50, of Hoboken, New Jersey was convicted of using a computer to commit a crime and unlawful posting of messages. Officials said the threats were sent via email to Treasurer Michael Schostak, asserting affiliation with Hamas, child sexual exploitation and more.

At the time of his arrest, police said Aisen was a resident of Marblehead, Massachusetts.

As previously reported, nearly 200 people received the emails, sent between July and October of 2023, according to the Bloomfield Township Police Department. Police said Schostak initially ignored the emails, but after they escalated and included his family members, friends and colleagues, he filed a complaint.

Aisen underwent a court-ordered forensic evaluation in 2024 and was found to be incompetent but restorable. In 2025, he was determined to be competent for trial.

Oakland County Circuit Judge Yasmine Poles presided over the trial, which started May 11 and ended May 12. The sentencing hearing is scheduled for June 9.

Using a computer to commit a crime is punishable by up to four years in prison and/or a $5,000 fine. Unlawful posting of messages carries a penalty of up to two years in prison and/or a $5,000 fine.

Aisen is in the Oakland County Jail, with bond set at $50,000.
