Opening arguments: Grandmother insane or seeking revenge?

A jury must decide which Carmela Dela Rosa threw her 2-year-old granddaughter to her death from a mall walkway: a spiteful woman who was seeking revenge or one who was psychotic after years of mental illness.

Those were the two versions prosecutors and defense attorneys depicted Monday during the first day of Dela Rosa’s trial in Fairfax County Circuit Court. Dela Rosa, 50, is charged with murder in the Nov. 29, 2010, death of Angelyn Ogdoc, who died after being thrown from a sixth-floor walkway at the Tysons Corner Center.
