Carmela Dela Rosa allegedly threw two-and-a-half-year-old Angelyn Ogdoc off a sixth floor outdoor walkway at Tysons Corner Center around 7:15 p.m. Monday, Fairfax County Police spokesperson Tawny Wright tells WTOP.
Dela Rosa was arraigned Tuesday morning at Fairfax County Circuit Court. She is due back there on Jan. 4.
She is currently being held without bond at the Fairfax County Adult Detention Center.
Dela Rosa, of Fairfax, was walking with other family members Monday when she picked up and threw the girl off the walkway in a matter of seconds, Wright says.
Emergency responders took Ogdoc to Inova Fairfax Hospital, where she later died. Police were notified of her death around 4:30 a.m. Tuesday.
Dela Rosa was originally charged with aggravated malicious wounding, but the charges were upgraded to murder following the girl's death.
There is a security camera on the walkway. There is no word on whether the camera captured the incident.
The walkway connects Parking Garage E with the movie theaters and a food court. There is a railing just higher than waist-level.
Police have not said what prompted the Dela Rosa to hurt her granddaughter.
Dela Rosa's neighbors say she often took care of her granddaughter, and was recently rushed to the hospital because she was sick.
"She's like a normal person, you wouldn't think something like that would happen," next-door neighbor Russell Jackson tells WTOP.
"I've seen her picture, but I'm still saying 'They've got the wrong house.'"
