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.

The search for Austin Drummond started on July 31, two days after a baby was abandoned and four family members were found dead in another TN county.

A manhunt for the suspect in the Tennessee kidnappings and killings of four people, including three from the same family, ended Tuesday, police said.
