FALLBROOK, Calif. -- A Fallbrook man whose wife caught him looking at alleged child pornography on his computer was under arrest Friday, according to the sheriff's department.

Todd David Norton, 43, was arrested at his home in the 4100 block of Deluz Road Thursday afternoon after deputies executed a search warrant and found alleged child pornography on his computer, said San Diego County sheriff's Detective Dan Laibach.

Norton's wife called authorities Monday to say that she had left her husband of four years because she caught him watching a movie clip of two pre-teen girls touching each other, Laibach said.

She said that after she left him, he left threatening and harassing voicemail messages on her cell phone stating he would hurt her if she took their child, Laibach said.

Norton was booked into the Vista jail on $50,000 bail, according to jail records.

On his MySpace page, Norton lists his occupation as rancher/construction and says he is a proud parent who graduated from Millikan Senior High School in Long Beach in 1984.
