Medford, OR -

A man already in jail on sex charges is now facing 24 counts related to child pornography.
The Mail Tribune reports that Michael Dean Murray of Medford pleaded not guilty Thursday to 24 counts of encouraging sex abuse -- the criminal charge related to child pornography -- in Jackson County Circuit Court in Medford.

Investigators say they found images on his computer of children engaged in sex acts. Police did not say where the children were from.

Murray was arrested in September on two counts of sodomy.

The grand jury indicted him on Monday.
