RADFORD, Va. (AP) - A Radford University student accused of stabbing her roommate to death has waived her right to a preliminary hearing, sending the case to a grand jury.

Police charged 21-year-old Luisa Ines Tudela Harris Cutting with second-degree murder in the slaying of 20-year-old Alexa Cannon. Police say Cutting confessed to the stabbing when officers found her covered in blood in their off-campus apartment in January.

A judge sent Cutting's case to a grand jury Thursday to decide if it'll be tried in circuit court. Defense attorney Blair Howard told news outlets Cutting's mental state would likely be an issue.

Police said the two had a friendship that predated them living together. Warrants show police found evidence Cannon consulted others about problems with Cutting in the days before she was killed.
