Fernandez's sister, British-Filipino Ma. Aurora Moynihan, was shot dead before dawn on Sunday. Her body was dumped along Temple Drive near Giraffe Street in Brgy. Ugong Norte, Quezon City at around 1:55 a.m.
Moynihan had gunshot wounds in the chest. A cardboard sign was found on top of her body with the sign "Drug pusher ng mga celebrities, kasunod na kayo!"
Fernandez said her family's priority now is to protect Ma. Aurora's children.
"In the early hours of September 10th, we lost my sister Aurora Moynihan. We as a family have one priority and truth at this point in time and that is to protect her children from further pain and suffering so that they, and we as a family may take this time to grieve, mourn but most of all celebrate the life of this exceptional human being I will forever have the privilege of calling my sister," she said.
"Thank you for your understanding," Fernandez ended her statement.
Police investigation is still ongoing to determine who may be responsible for the shooting. —KG, GMA News
