MADRID A tragedy that should never have been turns even worse. Rocío Piñeiro was killed while hearing Mass with her mother on Thursday. No reason, just a madman. She was a week away from giving birth, so a Caeseran was performed on her body. The baby, named Álvaro by his family, died yesterday. In fact, the little boy had had to be revived on his way from the hospital as he was born with a cardiac arrest in progress and had been in intensive care at the hospital. "But we had to try," said Dr.Ceferina Cuesta López, who performed the operation.
