Assistant Special Agent in Charge Walter Brown confirmed this afternoon three people were found deceased inside a house in the 100 block of Kirkland Street.
Beyond the initial confirmation, Brown declined to immediately discuss circumstances.
Law enforcement sources said further SBI agents were en route to the scene.
Brown said the Halifax County Sheriff’s Office is assisting the SBI and Littleton Police Department in the investigation.
Crime scene tape blocked off both entrances to Kirkland Street.
A couple leaving a neighboring residence said they didn’t know any details.
