A north Florida mother has pleaded guilty to shaking her baby to death after the boy's crying interrupted her game on Facebook.
Alexandra Tobias pleaded guilty to second-degree murder and was remanded in custody.
She reportedly told investigators she was angered because the boy was crying while she was playing the game FarmVille.
She told officers she shook the boy, smoked a cigarette to compose herself and then shook him again.
She will be sentenced in December. Guidelines call for 25 to 50 years in jail, but a prosecutor said it could be shorter than that.
