Olympics star Danielle Scott was injured last week in Baton Rouge, Louisiana, trying to protect her sister, Stefanie Vallery when Vallery’s husband attacked her with a knife, reports the Grio.com. The five-time Olympic volleyball star required surgery after she was stabbed multiple times trying to protect her sister (Stefanie Vallery) from her estranged husband on Sunday night. Vallery, 51, did not survive the attack and police are now searching for Michael Vallery 49. The couple was separated but hadn’t finalized their divorce, according to reports. When he showed up at her home in Baton Rouge, La., he became enraged during a heated argument and unleashed a violent assault on his ex. Scott was also injured in the attack. “He was in a rage. … Things escalated a little more. He left out the house and then (about three minutes later) came back through a window,” Scott told the Baton Rouge Advocate. “He started stabbing her and we were pulling him off of her and fighting for the knife. We were trying to put pressure on the wounds, but she had already passed. Then he kicked down the door and came back again. I turned to him and said: ‘You killed my momma.’ He just didn’t care — he ran up and stabbed (her) some more and ran out.”
