CONROE, Texas (AP) - The state s highest criminal court has reversed a trial judge s decision to allow additional DNA testing of evidence that a death row inmate contends could show he s not responsible for the slaying of suburban Houston college student more than 15 years ago.

The Texas Court of Criminal Appeals on Wednesday said convicted killer Larry Swearingen hasn t established that biological evidence he wants tested could change the outcome of his trial for the abduction, rape and strangling of 19-year-old Melissa Trotter.

State District Judge Kelly Case allowed the testing. Montgomery County prosecutors appealed the decision.

Trotter s body was found in January 1999 in the Sam Houston National Forest south of Huntsville, nearly a month after she was last seen leaving the library at what is now Lone Star College.
