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.

After a week-long, multi-agency manhunt, the man believed to be responsible for four deaths was arrested in Jackson, Tennessee.

Drummond's criminal past stretches over a decade into the past, as he was convicted of aggravated robbery in 2014 after robbing a convenience store in Jackson, Tennessee the year prior, according to WREG-TV in Memphis. The suspect spent 13 years behind bars, during which he picked up an additional charge for retaliation, according to Fox News.
