Renato Seabra, the alleged killer of Portuguese gay journalist Carlos Castro, asked a judge on Friday to toss out his murder confession.

Defense lawyer David Touger argued that Seabra did not mean to admit to brutally attacking Castro for more than an hour and castrating him with a corkscrew, the New York Daily News reported.

Touger suggested that his client unintentionally waived his right to remain silent. “Maybe [it was] not his dialect of Portuguese,” Touger said of the interpreter provided by authorities. “I don't think he knowingly waived his constitutional rights.”

Manhattan Supreme Court Justice Charles Solomon granted Touger's request to hold hearings on whether Seabra's confession will be permitted as evidence, but denied a motion to dismiss murder charges.

Touger had previously argued that Seabra's confession should be thrown out on the grounds that nobody witnessed Castro's January 7 murder in the Inter-Continental New York Times Square Hotel room that Castro and Seabra shared.

Seabra reportedly confessed to officials that he killed Castro in a fit of rage. The 21-year-old fashion model has been accused of bludgeoning to death and castrating with a wine corkscrew the 65-year-old Castro as the men vacationed over the New Year holiday.

Seabra has not discussed whether he was romantically involved with Castro, as friends have said and Facebook postings suggest. His mother, however, insists her son is not gay.

Seabra earned fame last year on the Portuguese reality talent contest A Procura Do Sonho, or Pursuit of a Dream. He didn't win the contest but was signed to a modeling contract.

Castro had written articles and books about fashion and was a vocal gay rights advocate.
