Brittany Pilkington admitted to killing her three sons and was sentenced to 37 years to life in prison after pleading guilty on November 20, 2019 in Ohio.

Brittany smothered her three sons, Niall, Gavin and Noah, to death over a 13-month period. Niall, 3 months, died in July 2014; Gavin, 4, died in April 2015; and Noah, 3 months, died in August 2015. Brittany used blankets to suffocate her 3 kids.

Brittany initially said she believed genetics played a role in the deaths of the boys but she later admitted to suffocating them to death.

Her defense team said that test results showed Brittany's brain has damage from severe abuse and childhood lead poisoning.
