HARRISBURG, Pa. -

The Pennsylvania attorney general's office is investigating the management of the National Museum of Industrial History in Bethlehem.

In a report released earlier this year, a Northampton County grand jury said the the head of the yet-to-be-built museum, Stephen Donches, had mishandled millions of dollars in donations over a number of years.

A month later, Donches resigned as president and CEO, but he's still an employee of the organization.

He's never been charged in the case, but now the Pennsylvania attorney general's office is on the case, investigating to determine whether there was any wrongdoing on the part of the museum's board of directors.
