A Marblehead, Massachusetts, man who flooded Bloomfield Township inboxes with months of hostile messages is now facing prison time after an Oakland County jury found him guilty on two felony counts.
Jurors on Monday convicted 50-year-old Marc William Aisen of unlawful posting of a message and using a computer to commit a crime after a trial that started on Monday and wrapped up yesterday. He is being held at the Oakland County Jail on a $50,000 bond, with sentencing currently set for June 9, according to prosecutors and court records.
The conviction followed testimony and exhibits that prosecutors said showed a steady escalation: what began as a single email aimed at Bloomfield Township Treasurer Michael Schostak allegedly morphed into a broad campaign targeting Schostak’s family, colleagues, and local groups, The Oakland Press reported. The case was tried in Oakland County Circuit Court before Judge Yasmine Poles, and jurors returned guilty verdicts on both counts they were asked to consider, the outlet noted.
Police and local media say Aisen’s messages went out between July and October 2023 and ultimately reached nearly 200 people, including township officials, community organizations, members of Schostak’s family, and his children’s school. Investigators told WXYZ they warned Aisen to stop, but say he kept sending accusatory emails anyway, alleging ties to Hamas and child sexual exploitation.
Competency Fight and Court History
Behind the scenes, the criminal case has been shadowed by a tangle of competency questions and federal filings. A 2024 court-ordered forensic evaluation found Aisen incompetent but restorable, according to state court materials, and his legal team turned to federal court to challenge aspects of his state prosecution.
The federal docket and a written opinion lay out a detailed timeline of those competency findings, motions, and rulings. A compilation of the federal filings and the state register of actions is available through Justia and related coverage.
What He Was Charged With
Aisen’s convictions line up with two Michigan statutes that deal specifically with electronic communications. One covers unlawful posting of a message, and the other involves using a computer to commit a crime. Under state law, those offenses can be prosecuted as felonies and can carry additional penalties when electronic tools are used.
The unlawful-posting law and the computer-use provisions are contained in the Michigan Compiled Laws. As set out by the Michigan Legislature, the key sections in this case are MCL 750.411s and the computer-use provisions in chapter 752.797/752.796.
Reaction From the Treasurer and Township
Schostak has publicly said the line was crossed when the emails moved from rough political criticism to deeply personal attacks that pulled in his family and his kids’ school. At that point, he has argued, it stopped looking like civic debate and started looking like targeted harassment.
His comments, along with a detailed timeline of the messages and the October 2023 arrest and arraignment, were documented in earlier coverage by Downtown Newsmagazine, which tracked the case from its early stages.
What to Watch Next
Sentencing is set for June 9, and defense attorneys could use that hearing to argue for mitigation or file immediate post-trial motions. Aisen has already taken a run at federal relief: a federal judge dismissed his habeas petition in April 2025, according to court records.
The case has also produced appellate filings, and with fresh felony convictions now on the books, additional appeals after sentencing remain very much on the table.
