In June, officers discovered their bodies inside a home on the 2200 block of Wolfe Street in Brunswick, Georgia during a welfare check. They didn't find any suspects and issued a $15,000 reward for answers.

The GBI said the investigation is still ongoing and that it believes there may be additional people connected to the crime. The GBI also said it isn't going to comment on the relationship between the suspect and the victims.
