Seward's son, Frederick, was brutally beaten while trying to keep Powell from his father's door.In 1980, he suffered a heart attack in prison and was allowed to leave the country two months later by Marcos's wife, Imelda.He spent the next three years in exile near Boston before deciding to return to the Philippines.Rathbone lunged at him, and though slashed in the arm, forced the killer to the railing.Booth leapt from the balcony and caught the spur of his left boot on a flag draped over the rail, and broke a bone in his leg on landing.Powell slashed the secretary's throat twice, then fought his way past Seward's son Augustus, an attending hospital corps veteran, and a State Department messenger.Powell escaped into the night, believing his deed complete.Although Marcos was officially declared the winner of the election, widespread allegations of fraud and illegal tampering on Marcos's behalf are credited with sparking the People Power Revolution, which resulted in Marcos fleeing the country and conceding the presidency to Corazon Aquino.Although many, including the Aquino family, maintain that Marcos ordered Aquino's assassination, this was never definitively proven.Though injured, he rushed out the back door, and disappeared into the night on horseback. Charles Leale, immediately went upstairs to the box. At almost the same moment Booth fired the fatal shot, his accomplice, Lewis Powell (alias Lewis Paine, Lewis Payne), attacked Lincoln's secretary of state, William Henry Seward, at his home on Lafayette Square.The bullet had entered through Lincoln's left ear and lodged behind his right eye. He was carried across Tenth Street, to a boarding-house opposite the theater, but the doctors' best efforts failed. Seward lay in bed, recovering from a carriage accident.
