JACKSONVILLE, Fla. ( KTLA) -- A Florida mother accused of shaking her baby to death after he interrupted her Farmville game on Facebook has pleaded guilty to second-degree murder.

Alexandra V. Tobias, 22, is charged in the January death of 3-month-old Dylan Lee Edmondson. She entered her plea on Wednesady.

Tobias told investigators she became angry after the baby cried while she was playing the computer game and she shook him, the Florida Times-Union is reporting.

She also said she smoked a cigarette to compose herself and then shook the baby again, at which time he may have hit his head, the paper reported.
