A Multnomah County, Oregon grand jury has indicted twin brothers on charges of encouraging child sex abuse.
They're both accused of possessing and distributing child pornography.
Steven Lin Stryker and David Neil Stryker, both 56, each face a 10-count indictment, charging them with first-degree encouraging child sexual abuse.
Steven Stryker is accused of unlawfully possessing and viewing sexually-explicit conduct involving children between January and March 2014. His brother is accused of the offenses in August 2011, May 2013 and last March, according to the indictments.
On Thursday afternoon, Steven Stryker entered not guilty pleas to the 10 charges after his arrest on Wednesday afternoon.
A warrant has been issued for his brother's arrest.
Court records indicate that Steven Stryker works full-time as a ''railroad operator,'' and lives in Southeast Portland. He has one prior felony burglary conviction in California from more than three decades ago.
The brothers live together near Southeast Powell Boulevard and 168th Avenue, according to court documents.
Steven Stryker is being held at the Multnomah County Detention Center on $200,000 bail and is due back in court on Feb. 20.
