Austin Drummond, charged in connection with the July 29 quadruple homicide in Lake County, is being held without bond as state seeks death penalty.

At the news conference Tuesday, Tennessee Bureau of Investigation Director David Rausch said the suspect’s girlfriend was related to the victims. Goodman later confirmed to CNN Drummond’s girlfriend and Rose were sisters.

Prosecutors plan to seek the death penalty against a Tennessee man charged with killing the parents, grandmother and uncle of an infant found abandoned in a home’s front yard.
