ZANESVILLE: An appeals court in eastern Ohio has overturned the convictions of a woman and her husband in the drowning of her 3-year-old son and disappearance of his 2-year-old brother during a camping trip.

The court ordered that Kasey and Richard Klein Jr. of Zanesville be tried again. They had been sentenced to 12 years in prison for involuntary manslaughter last year.

The appeals court determined the lower court wrongly tried the pair together. Richard Kleinís attorney says that hindered his ability to get a fair trial.

Authorities say the toddlers wandered away from the family campsite near the Muskingum River at Ellis Dam in 2011. The 3-year-oldís body was found in the water. His half brother wasnít found.

Messages left Tuesday for prosecutors and Kasey Kleinís attorney were not immediately returned.
