A US mother in Ohio admitted killing her three young sons in separate incidents over the past 13 months because her husband paid more attention to the boys than a daughter, police said.
Brittany Pilkington called 911 shortly after 3:00 am Tuesday to report that her three-month-old baby, Noah, wasn't breathing.
Police said they immediately began a "tedious investigation" because it was "the third such incidence at this same residence involving similar circumstances."
Another three-month-old son, Niall, was found dead by father Joseph Pilkington when he came home from work in July last year. The cause of death was not determined.
Then on April 6, the father came home to find their four-year-old son, Gavin, was also dead.
Brittany Pilkington was charged with murder after she confessed "she intentionally killed all three of her sons," police said in a statement.
She reportedly killed them by putting a blanket over their heads and suffocating them because her husband paid more attention to the boys than he did their daughter, who will turn four later this month.
