A grand jury may hear brutal details in the case of a teenage girl's murder in Tullahoma.
Thomas Allen's charges have been bound over to the grand jury, after a day of chilling testimony about the killing of 19-year-old Megan McGuinn in March.
An investigator testified McGuinn suffered 18 deep cuts to her head, torso and legs.
The suspect lived with the victim and her boyfriend and police say he stole money from the couple's apartment after the killing.
