Mom claims she killed 3 young sons in 13 months

21-year-old Brittany Pilkington

Brittany Pilkington, 23, has been charged with three counts of murder and jailed, after confessing to killing her three sons in a space of 13 months.
Pilkington was said to have calmly called 911 on Tuesday to report that her son, 3-month-old Noah Pilkington, wasn’t breathing. Hours later, she confessed to killing him together with two other young sons, 4-year-old Gavin Pilkington, who died in April, and 3-month-old Niall Pilkington, who died in July 2014, the Associated Press reports.
Bellefontaine Police said officers went to the family's apartment on Tuesday morning after an emergency call from the mother saying that Noah wasn't breathing. They said she calmly answered a dispatcher's questions while the baby's sleep apnea alarm beeped in the background. The baby was pronounced dead at a hospital.
Authorities already were investigating what happened to Niall and Gavin, whose causes of death still hadn't been conclusively determined. In each of those cases, their father, Joseph Pilkington, found them unresponsive when he got home from work.
Joseph and Brittany Pilkington were cooperative on Tuesday, police said. She eventually told detectives that she killed all three children, police said, but no other details of officers' discussions with her were released.
