A Harrison Township woman was sentenced yesterday to 9 to 15 years in prison after a jury convicted her of involuntary manslaughter in a December 2024 crash that killed a 69-year-old Sterling Heights man. During a brief trial in May, jurors acquitted her of a second-degree murder charge but found her guilty on the lesser manslaughter count. She also pleaded no contest to an assault and obstruction charge tied to her arrest.
Verdict and sentence
Jurors deliberated just over 48 hours before convicting 27-year-old Diamond Leann Glenn of involuntary manslaughter, according to ClickOnDetroit. The jury cleared Glenn of second-degree murder and an attempted failure-to-stop charge, the outlet reported. The court credited her with 565 days already served and accepted her no-contest plea on the assault and obstruction count.
Prosecutors' account of the crash
In a summary of the case, the Macomb County Prosecutor's Office said Glenn was driving recklessly near the intersection of Mound and Chicago roads on Dec. 21, 2024, when her Ford Escape struck a Chevrolet Silverado driven by 69-year-old Christopher Andelean of Sterling Heights, who later died, according to a press release from the Macomb County Prosecutor's Office. “This case is a tragic reminder that reckless decisions behind the wheel can have devastating, irreversible consequences,” Prosecutor Peter J. Lucido said in the release. The office also noted that witnesses at the scene detained Glenn until police arrived.
Officer bitten during arrest
Local coverage at the time of the crash reported that officers found Glenn on a sidewalk and that she bit and resisted an officer while being taken into custody, requiring medical attention before she was transported, according to FOX 2 Detroit. That initial reporting also noted that her bond was set at $100,000 and that she would be required to wear an alcohol tether if released.
Case timeline and next steps
Glenn was bound over to Macomb County Circuit Court in September 2025 on charges that included second-degree murder, involuntary manslaughter and attempted failure to stop after a preliminary exam, court records show. The case went to trial in May 2026 and concluded this week with the manslaughter conviction and the 9-to-15-year sentence, as reported by ClickOnDetroit.
Prosecutors frame outcome as accountability
Macomb County officials said the prosecution sought to hold the driver accountable and to secure justice for the victim's family, according to the county's statement from the Macomb County Prosecutor's Office. The press release recapped the charges and the December 2024 crash that triggered the investigation.
