Sexual Abuse in the Diocese of Saginaw
The Diocese of Saginaw was among the Michigan dioceses whose files were reviewed after the Attorney General’s 2018 clergy-abuse investigation began. White Law PLLC works as a Michigan clergy sexual abuse lawyer for survivors whose abuse occurred in parishes, schools, and rectories like those tied to Father John Hammer.
The state’s seven dioceses, Diocese of Saginaw, Diocese of Marquette, Diocese of Gaylord, Archdiocese of Detroit, Diocese of Lansing, Diocese of Grand Rapids, Diocese of Kalamazoo, have each faced scrutiny over their handling of abuse claims. Reports issued by the Attorney General, including the one covering the Diocese of Saginaw, form part of the public record on Father John Hammer.
The Allegations Against Father John Hammer
What the Record Shows
John (Jon/Jack) Hammer ended his tenure at the Diocese of Saginaw, which accepted him after he was unable to continue working in dioceses in Ohio and Maryland following abuse allegations. He was stripped of his faculties in Baltimore in 1990, yet the Diocese of Saginaw gave him assignments for twelve more years. Lawsuits filed on behalf of survivors allege that Saginaw leadership may have known about Hammer’s behavior as early as 1978, before his alleged abuse of multiple children. Public records list Hammer under the Diocese of Youngstown, Ohio, though most of his ministry was in Saginaw.

Criminal vs. Civil Sexual Abuse Cases
Survivors often ask whether they should pursue a criminal case, a civil case, or both after abuse by someone like Father John Hammer. A criminal case is brought by the state and can lead to prison time for the offender; a civil lawsuit is filed by the survivor and seeks financial compensation. The two paths are independent, one can proceed even if the other cannot.
Michigan civil courts allow survivors to sue both the individual abuser and the institutions that enabled him. That means claims connected to Father John Hammer can target his estate as well as the diocese or religious order, particularly where leaders knew or should have known of the danger, failed to prevent it, covered up reports, or screened and trained clergy inadequately. Damages can include medical and therapy costs, pain and suffering, and emotional distress.
Statute of Limitations on Clergy Sexual Abuse Cases in Michigan
The civil filing window in Michigan comes from Michigan Legislature §600.5805, ten years, or until the survivor reaches 28, and it applies to abuse by clergy such as Father John Hammer. Criminal accountability works differently: the state faces no deadline for first-degree criminal sexual conduct charges.
Survivors frequently need years to process what a priest like Father John Hammer did to them. Trauma can fragment or hide memories, and fear of not being believed keeps many silent. The extended deadlines in Michigan law exist precisely for this reason, and an early conversation with an attorney costs nothing to explore.
