A Florida jury on Friday convicted the husband of boxer Christy Martin for attempted second-degree murder, the Orlando Sentinel reported.
James Martin, 68, was found guilty of all three counts against him.
Christy Martin, who once made the cover of Sports Illustrated, was stabbed and shot Nov. 23, 2010.
"I don't think it's hit me yet," said Christy Martin, who uses her maiden name, Salters, when she's not boxing. "To be honest with you, I'm almost speechless."
During the trial, the jury spent three days listening to witnesses, including Christy Martin and Sherry Jo Lusk.
Christy Martin was planning to leave her husband for Lusk, prosecutors said. James Martin responded with threats and later attacked his wife.
"This is Christy's biggest win of her life," said prosecutor Ryan Vescio, according to the Sentinel.
James Martin, who faces up to life in prison, will be sentenced on June 26.
