(NBC News) Charges were dropped Tuesday against the Mississippi man suspected of mailing ricin-laced letters to President Obama and other public officials - as authorities searched the home of another man hoping to find clues in the expanding investigation.

"I respect President Obama and love my country. I would never do anything to pose a threat to him or any other U.S. official," Paul Kevin Curtis said at a news conference Tuesday.

Curtis was arrested last Wednesday at his home in Corinth, Miss. Two letters that initially tested positive for ricin, a poison, had been found earlier in the week -- one addressed to Sen. Roger Wicker, R-Miss., and one to President Obama.

"This past week has been a nightmare for myself and my family. My mother has suffered, as well as my children. I would like to get back to normal, which for me means being the best father I can to my children," Curtis said.
