A tense moment in a Macomb County courtroom has turned into a long prison stretch. Today in Mount Clemens, a Rochester Hills man was ordered to serve more than seven years in state prison after admitting to a case tied to threats against a Macomb County judge. Prosecutors say the punishment stems from a false terrorism report that followed a heated outburst during an earlier sentencing hearing, and the court refused to let the defendant take back his guilty plea before imposing the term.
According to The Oakland Press, court filings show Jamar Devante Warren pleaded guilty in January 2025 to making a false report of terrorism. Today, he was sentenced in Macomb County Circuit Court to a prison term recorded as more than seven years to 20 years. The outlet reports that Warren tried to withdraw his plea during the hearing, but the judge dismissed the request.
The case stretches back to November 16, 2022. While Warren was being sentenced on unrelated charges that day, he allegedly threatened to shoot Macomb County Circuit Court Judge Kathryn Viviano, ClickOnDetroit reported in 2023. Prosecutors responded to that outburst by filing the terrorism-related count and associated computer-use allegations in the months that followed.
Prior conduct and related penalties
Court records and prior reporting indicate that Warren already had a record of assault-related cases and had accumulated roughly three years and five months behind bars before this latest sentence, according to The Oakland Press. Separate entries show a 93-day sentence after a no-contest plea to three counts of assault and battery, along with one-to-four-year terms on two counts of assault with a dangerous weapon. Authorities say he was on parole when he made the threat in Judge Viviano's courtroom and that in August 2024 he was accused of throwing suspected urine at an officer through a cell food port.
Charges and legal exposure
Warren's conviction for making a false report of terrorism falls under Michigan's anti-terrorism law, which treats a false report or terrorist threat as a felony punishable by up to 20 years in prison and a fine. The statute and its maximum penalty are spelled out in the text of the Michigan Legislature.
The sentence was handed down at the Macomb County Circuit Court building in Mount Clemens, where Judge Anthony R. Servitto presides. Public information from Macomb County Courts lists the courtroom assignment and procedures for Servitto's docket. State officials will apply credit for the time Warren has already served when they calculate his new prison term.
