Baby sitter on trial in death of boyfriend's daughter, 2

CLEARFIELD, Pa. (AP) -- A Pennsylvania woman is on trial on charges she killed her boyfriend's 2-year-old daughter while baby-sitting her.

Twenty-five-year-old Cody Lander testified Monday that he and the defendant, 22-year-old Jennifer Medzie, argued the night before his daughter, Sophia, was injured. Lander says Medzie complained the girl "always cried for her," and Lander says Medzie told him he had to choose between being with the girl or with Medzie.

Police and doctors say Sophia had been shaken violently while Medzie was watching her at a Bradford Township home Nov. 15, 2013. Medzie told police the child fainted in her arms.

The child reportedly had the flu the night before she became unresponsive. Medzie has denied the first- and third-degree murder charges she faces.
