ARCHIBALD, Pa. (WPVI) -- Police say an 18-year-old Pennsylvania man told them he'd been drinking all day before he yanked his 6-week-old daughter's arm while changing her diaper, which investigators say broke it.
Archibald police say Kylie Jacob-Mlyczk was arrested and jailed Tuesday on charges of aggravated assault, child endangerment and indecent assault.
Police say the suspect was alone watching the girl on Monday when she was injured. Police say the suspect initially told them the girl hurt the arm by rolling over onto it, but police say the child is still too young to roll over on her own. Police say the suspect then acknowledged grabbing the girl's arm and that he may have tugged it too hard in the process.
Online court records don't list an attorney for Jacob-Mylczk, who remained in the Lackawanna County jail on Wednesday.
