Assistant U.S. Attorneys Andrew Cogar and John Parr filed a complaint for forfeiture of the Bridgeport home owned by Tamm.
The criminal action complaint said Tamm allegedly engaged in a four-year scheme to commit mail and wire fraud by using state funds to purchase items.
He would then sell for his own benefit.
U.S. District Judge Irene M. Keeley granted a protective order for the property on June 13.
The complaint said the Federal Bureau of Investigation discovered that Tamm used state-issued government purchasing cards (P-Cards) to purchase more than 300 computer switches from Pomeroy, an electronics company in Lexington, Kentucky. He did that several times between June 2008 and November 2012.
He resold the switches for approximately $638,500, according to the complaint.
Tamm purchased the property at 102 Rosewood Court in April of 2012 with the money he obtained through his mail and wire fraud scheme, according to the complaint.
He closed on the property for $435,000. The Deed of Trust indicates that Tamm mortgaged the property for $342,500.
A search warrant was served on Tamm's Rosewood Court home on April 3.
The complaint said Tamm was questioned by an FBI agent on May 30. Tamm told agents that 'he was not a bad person, but that he just made bad decisions."
Tamm also told agents he was in the process of updating his wife's grandmother's home so that his wife and children would have a place to stay while he was gone, according to the complaint.
No charges have been filed at this time, but the federal government believes it has proof that Tamm is guilty.
