RAPID CITY, South Dakota — A former priest convicted of stealing $260,000 in cash donations from the Diocese of Rapid City is now accused of having sexual contact with a minor and possessing child pornography.

The Rapid City Journal reports Marcin Garbacz, 42, was indicted in February but the case was only unsealed on Friday.

Garbacz is charged with “engaging in illicit sexual conduct in a foreign place” between June 21 and July 7, 2011, by traveling to another country and having sexual conduct with a boy under the age of 18.

The Diocese of Rapid City said in a statement that it is cooperating with the investigation.

Garbacz is scheduled for a sentencing hearing on Monday after a jury convicted him in March of 65 financial crimes. He faces to up to 20 years in prison on each of the 59 wire fraud and money laundering counts, up to 10 years for transporting stolen money and up to three years for each of the five tax crime charges.

The new charges stem from an FBI agent coming across child pornography on one of Garbacz’s thumb drives during the financial crimes investigation, according to court records.

Prosecutors said Garbacz spent the stolen money on expensive artwork and religious objects, a diamond ring, a grand piano, a Cadillac and other items.

Garbacz served as a chaplain and teacher for the Rapid City Catholic Schools System during that time, a prosecutor said during his trial.
