McLEAN, Virginia -- A toddler has died after police say she was thrown six stories off a shopping mall walkway by a woman believed to be her grandmother.

Police said the 2 1/2-year-old girl fell Monday night from a walkway that links the mall to a parking garage at Tysons Corner Center in Virginia. The girl was taken to a hospital where she later died.

Fairfax County police spokeswoman Tawny Wright said 50-year-old Carmela Dela Rosa was arrested and charged with aggravated malicious wounding. Wright said the charge will be amended to murder now that the girl, Angelyn Ogdoc, has died.

Wright said the toddler and Dela Rosa were leaving the mall with family when Dela Rosa allegedly picked the girl up and threw her off the walkway.
