On Thursday, a Fairfax County jury found Carmela dela Rosa guilty of first-degree murder, determining she understood what she was doing when she dropped her 2-year-old granddaughter off an elevated walkway at Tysons Corner Center last year. She was sentenced to 35 years in prison.

Now, surveillance video from Tysons Corner Center that was used to convict dela Rosa has been released, which shows her throwing the child off the bridge. The footage is graphic and disturbing.
