A Springdale woman has been sentenced to six months of work release and fined $2,000 in the heat stroke deaths of her two children who had locked themselves in the trunk of a car.

Twenty-five-year-old Katrina Markley pleaded guilty Monday to two misdemeanor counts of third-degree endangering the welfare of a minor in the deaths of 5-year-old Curtis Markley and 4-year-old Virginia Markley. She was sentenced to six months of work release that involves supervised community service work during the day and nights spent in a barracks-style building at the county jail.

Police say Markley admitted she was on the computer most of the day when her children locked themselves in the trunk of a car in June 2009 and died of heat stroke.
