St. Joseph County police have launched a criminal investigation into the Olive Township trustee's office, after irregularities were discovered in a recent audit of the township's finances by the State Board of Accounts.

As NewsCenter 16 was first to report earlier this month, the state audit accuses elected trustee John Michalski of withdrawing money from the township account.

There were seven separate withdrawals at atm's at three casinos from December of 2009, to November of 2011 totaling more than $1,600.

All of that money has since been repaid by the trustee.

In fact, Michalski has taken a total of $7,600 out of his own pocket to replenish township accounts for various personal and/or undocumented expenditures.

Still, a copy of that audit was sent to the prosecutor's office for review and now police are investigating with assistance from the state board of accounts.

If they determine that a crime has been committed, the evidence will then be presented to a grand jury.

Meanwhile, the state is also seeking another $7,600 from Michalski to cover the costs of the audit, which took more time than it should have because of poor record keeping.
