The Florida Supreme Court on Thursday upheld Labrant Dennis' murder convictions and death sentence.

Dennis was convicted of fatally beating Timwanka Lumpkins and Hurricanes linebacker Marlin Barnes with a broken shotgun in April 1996. Both died from massive head trauma.

Jurors voted 11-1 to recommend the death penalty.

The Supreme Court denied an initial appeal in 2002.

In the new case, the justices rejected Dennis' claims his lawyer was ineffective and had a conflict of interest and that a prosecutor made improper comments throughout his trial.

Dennis and Lumpkins had a child together.
