MADISON, Wis. (AP) – The Wisconsin Supreme Court has upheld child porn convictions in two separate cases, overturning earlier rulings. In the case of Jeremiah Purtell, the court said Friday that his probation officer’s warrantless search of his home computer that turned up child pornography did not violate his constitutional rights against illegal search and seizure. The court, in a 5-2 decision, reversed a decision by the state appeals court tossing Purtell’s four convictions for possessing child pornography. The 28-year-old from Hartford was sentenced to 12 years in prison. In the other case, the court in a 4-3 decision reinstated a conviction against James R. Hunt, of Fort Atkinson, for causing a child under age 13 to view sexual activity. The case involved images on Hunt’s cellphone that a 12-year-old girl saw.
