A 22-year-old woman in Jacksonville, Florida named Alexandra V. Tobias has pleaded guilty in the death of her 3-month-old son, Dylan.

The reason for such a despicable act? She tells investigators that she was busy playing the highly popular Facebook game, Farmville, when the child started crying. She explains that she became so angry, she shook the baby, went and smoked a cigarette to try and calm down, and then shook the baby more. She also added that while she was shaking him, he might have hit his head on something.

Tobias has been charged with second-degree murder, and could face up to life in prison…though it is noted that this sentence could be much, much less because “state guidelines” place the charge at 25-50 years imprisonment.
