A judge Tuesday imposed a life sentence on an Onalaska sex offender who had sexually graphic images of children.
The sentence for Donovan Cadogan, 31, is mandatory because of his prior conviction in La Crosse County Circuit Court.
Investigators arrested Cadogan in February 2011 after a five-month investigation revealed he uploaded 28 child pornography images to an online storage service using a public computer, according to the complaint.
“These are the type of images that further exploit children and further hurt children,” Assistant District Attorney Amesia Xiong said. “It is necessary Mr. Cadogan be warehoused to protect the community from himself.”
A La Crosse County jury convicted Cadogan of sexual exploitation of a child as a persistent repeat offender and possession of child pornography as a repeat offender after six hours of deliberation and a 2½-day trial.
“I may have been found guilty of this crime, but I did not in fact commit it,” Cadogan said.
At the time of his arrest, Cadogan was on extended supervision for a 2001 child enticement case where he exposed himself to an 8-year-old girl and tried to coax her to remove her clothing. He served eight years before his release and was re-confined in 2011 to another eight years when he violated his release.
Cadogan is addicted to pornography and revealed during a pre-sentence investigation that he victimized others as a juvenile, Xiong said.
Circuit Judge Todd Bjerke noted treatment has no effect on Cadogan, who sneaked pornography while on supervision and then denied doing so.
“You are a threat to any community you live in due to your consistent deviant sexual drive,” the judge said.
Bjerke also fined Cadogan $14,000 — or $500 for each image.
