A South Dakota man was arrested on Thursday after police found 114 guns as well as bomb-making materials inside his home, but at least one relative insisted to the Sioux Falls Argus Leader that he was victimized.

"They aren't going after criminals; they're going after guns," said a man identifying himself as the uncle of 29-year-old Darren Kyle Zafft. "I blame Obama for this."

Authorities also arrested 35-year-old Jennifer Marie Cash, who lived with Zafft. They were both charged with multiple counts of possession of a destructive device and possession of a controlled weapon.

The suspects also had around 10,000 rounds of ammunition, as well as grenades, and $20,000 in cash inside their home at the time of their arrest. Authorities executed a search warrant on their home after a neighbor reported finding a .22-caliber bullet casing inside their mattress.

"Dealing with these explosives that's something we don't normally do," said police spokesperson Sam Clemens. "We don't know if he was putting these components together in the home or in another place; that's one of the things we're working on. This could have been a very dangerous situation."

Clemens also said that, while possession of the firearms was not illegal, between 15 and 20 of the guns found inside the home had been modified illegally.

Zafft was served with two protection orders in 2006, and served a one-year jail sentence four years later after being convicted on two counts of reckless use of weapons. He is currently being held on a $1 million cash-only bond.

According to KSFY-TV, Cash works as an education assistant at a local elementary school. She is being held on a $5000 cash-only bond.
