MARSHALLTOWN, Iowa (AP) — A former central Iowa high school educator who taught for 30 years has been imprisoned for distributing child pornography. The Times-Republican reports that Glen Sedlacek, of Marshalltown, was sentenced Thursday to 11 years in federal prison. He’d pleaded guilty in October after prosecutors dropped two other counts. Prosecutors say Sedlacek had numerous computer files containing pornography of children younger than 12, dating back to March 2013.

U.S. District Judge Stephanie Rose also ordered Sedlacek to make restitution of $6,000 to a female minor identified as Lily and $3,000 to a girl identified as Chelsa. Prosecutors say the two had appeared in porn films he’d viewed in his Marshalltown home.
