Macon -- Police are waiting for the results of a lab test that could help determine who killed and dismembered a recent law school graduate.

Police spokeswoman Jami Gaudet said the FBI is conducting lab tests of blood, fiber, fingerprints and other evidence linked to the death of 27-year-old Lauren Giddings.

She graduated from Mercer University's law school in May and authorities say she was killed while she remained in Macon to study for the bar exam.

Police found Giddings' torso outside her apartment building on June 30.

Police have charged Giddings' neighbor and classmate, 25-year-old Stephen Mark McDaniel, on unrelated burglary charges. He has been named a person of interest in Giddings' slaying but has not been charged in the death.
