The former treasurer of the Hearthstone Historic House Museum in Appleton, Wisconsin, Steven Jahnke, has been accused of stealing over $70,000 from the museum's accounts. According to a criminal complaint, Jahnke admitted to using the museum's funds for personal expenses such as cruises, travel, and vehicle repairs over a period of several years while serving as the treasurer.

Why it matters

The theft of funds from a local historical museum is a serious breach of trust and can have significant consequences for the institution's ability to fulfill its mission and serve the community. This case highlights the importance of strong financial controls and oversight in nonprofit organizations to prevent such misuse of resources.

The details

An investigation by the museum's board members found suspicious transactions unrelated to museum operations, including payments for Jahnke's personal property taxes, Amazon purchases shipped to his home, and other personal expenses. After reviewing the financial accounts, the board identified approximately $70,792.32 in suspicious expenditures between 2023 and 2024. Jahnke admitted to 'embezzling funds to pay for his own expenses' and said he planned to make restitution.

• Jahnke served as the museum's treasurer for 6-7 years, starting around 2019.
• The suspicious expenditures were identified in 2023 and 2024.
• Jahnke is scheduled to appear in court on March 17, 2026.
