MURFREESBORO, Tenn. -- A Memphis woman has been sentenced to 29 years in prison for fatally stabbing a Middle Tennessee State University women's basketball player.

Rutherford County Circuit Court Judge Don Ash on Tuesday sentenced Shanterrica Madden of Memphis to 25 years for second-degree murder and four years for tampering with evidence. The sentences will be served consecutively.

Madden was convicted in May in the March 2, 2011, death of 21-year-old Tina Stewart at an off-campus apartment they shared.

At her trial, Madden acknowledged stabbing Stewart but claimed she had acted in self-defense against her larger and more athletic roommate.

Madden is 4 feet 11 inches. She told the jury that a fight in Stewart's bedroom became physical when the 5-foot-7 player began hitting her. Madden said she defended herself with a knife.
