The Fairfax woman charged with throwing her 2-year-old granddaughter 50-feet to the child's death faces trial today.
The murder trial for Carmela Dela Rosa is expected to last two weeks.
At a February preliminary hearing in Fairfax County court, a police officer who investigated the incident at Tysons Corner quoted Dela Rosa saying: "Yes, I did it. I threw the baby off."
The mother of the child victim, Mary Kathlyn Ogdoc, told the court she watched Dela Rosa drop her daughter Angelyn from the elevated bridge connecting a parking garage to Tysons Corner Center on Nov. 29.
Prosecutors say Carmela Dela Rosa's conduct was premeditated and that she was not insane when she tossed Angelyn Ogdoc off the sixth-level walkway following a family outing.
Public defender Dawn Butorac has said her client suffers from significant mental illness.
Jury selection in Fairfax County Circuit Court is expected to begin Monday morning, and opening statements may be heard Monday afternoon.
