SPOKANE, Wash.—A Spokane man has pleaded innocent to charges of trying to extort money from a former state legislator after a night of sex.

Cody Castagna, 27, pleaded innocent Jan. 14 to three counts of theft, two counts of extortion and one count of conspiracy to commit extortion.

Prosecutors contend in court documents that Castagna and three other men attempted to blackmail former Rep. Richard Curtis in October.

Curtis, a Republican from the southwest Washington town of LaCenter, said in police reports that he and Castagna had sex in a hotel room and that Castagna later took his wallet and threatened to expose him publicly if he did not pay $1,000.

Castagna has contended Curtis reneged on a promise to pay $1,000 for sex.

“I can’t believe I’m facing six felonies and he’s not facing anything,” Castagna said after the hearing.

Curtis, a married father who voted against gay-rights bills in the Washington Legislature, resigned his office a few days after the incident became public. He is cooperating with investigators and will not be charged, prosecutors have said.

According to court documents, Curtis met Castagna at the Hollywood Erotic Boutique in Spokane Valley, where Curtis also engaged in oral sex with another man. Curtis and Castagna later met in the Davenport Tower Hotel.

Curtis gave Castagna $100 before they engaged in sex acts, according to police reports.

Documents allege that Castagna later left the room with Curtis’ wallet, credit cards and Washington State Legislature ID. He called Curtis, demanding the $1,000 that Castagna claimed he was owed for having unprotected sex.

Later, Castagna called Curtis again and demanded an additional $800, according to police reports. But Spokane police detectives had already been alerted and broke up the transaction.

Also charged are Robert H. Fletcher, 20, Joseph L. Castagna, 25, and Brandon Burchell, 24. All are charged with second-degree extortion and conspiracy to commit second-degree extortion. All four defendants are free on $7,500 bond each.
