A Logan County judge has set a March 7 trial date for the Bellefontaine woman charged with suffocating her three sons over a 13-month period. 23-year-old Brittany Pilkington is being held on 1 million dollars bond. She has pleaded not guilty. Prosecutors say Pilkington confessed to killing her 3-month-old son last month, a 4-year-old son in April and an infant son last July. Prosecutors say say Pilkington was jealous of the attention her husband paid the boys.
