Paul Harvey, 46, cried during Friday's sentencing hearing in London as a prosecutor described his wife's death. Investigators found Gloria Laguna, 48, died because her skull was extremely thin in places, a congenital condition she never knew about.
Prosecutor Richard Whittam maintained Harvey did not intend his wife's death. Harvey called the police emergency number, saying his wife collapsed after he threw the remote control at her.
"It is clear to anyone the distress he was suffering at the time," Whittam said. "He was crying and he remained in considerable distress, including pleading with her to recover.
"When paramedics arrived, he said, 'What have I done?' and 'I think I have killed my wife. I threw a remote control at my wife's head.'"
Harvey, who pleaded guilty to manslaughter, said he and his wife had been drinking and using cocaine at their home in London in March when they began arguing.
