BELLEFONTAINE, Ohio | A prosecutor says three young boys in Ohio died because their mother decided to suffocate them, not because children’s services or the legal system failed.

Twenty-three-year-old Brittany Pilkington is jailed on murder charges in all three deaths in the last 13 months. No defense lawyer has been named.

Logan County Prosecutor William Goslee said Wednesday that Pilkington said she suffocated the boys because she wanted their father’s attention for her young daughter and herself.

Pilkington called 911 as her husband tried in vain to revive their last baby boy on Tuesday in Bellefontaine (behl-FOWN’-tihn).

Goslee says no one could have predicted Pilkington would kill her remaining son. A judge ordered the 3-month old returned to his parents from protective custody last week for lack of evidence in the earlier deaths.
