Fridley Man Sentenced for Failing to Report to Prison on Child-porn Conviction

A federal judge added 14 months Monday to the sentence of a Fridley man who didn't show up last fall to start serving a 180-month prison sentence. 

U.S. District Court Judge Donovan M. Frank could have tacked as long as 10 years onto Matthew Eric Linngren's prison time. 

Linngren, 38, fled to California instead of reporting for prison on Sept. 22, but authorities there picked him up on auto-theft charges two weeks later.  He on Jan. 13. 

Linngren's original sentence was for distribution of child pornography. He confessed to sending more than 600 explicit photos of minors to a Yahoo group in 2005 as part of a plea agreement last year.

Any charges on the alleged auto theft are up to California authorities, the U.S. Attorney's Office for Minnesota said in a statement.
