On January 3, 2008, authorities located Emerson's 1995
Chevrolet Cavalier, where they found various items such as her water bottle, a dog leash, and a police baton. A local drifter and then-unidentified
serial killer, 61-year-old man
Gary Michael Hilton, was announced as a
person of interest in her disappearance. On January 4, three days after Emerson and Ella were last seen, a witness at a
Chevron gas station called
DeKalb police and stated that "the guy you are looking for is cleaning out his van." The police quickly arrived on scene and were able to stop Hilton before he could bleach the interior of the van. Crime scene analysts obtained blood evidence that was matched to Emerson's
DNA. Hilton was subsequently arrested and charged with Emerson's murder. The same day, Ella was found alive wandering in a
Kroger parking lot in
Cumming and she was safely returned to Emerson's family. The next day, more of Emerson's belongings would be found in a dumpster near a
QuikTrip elsewhere in the city: her bloodied clothing, wallet, driver's license, a
University of Georgia ID card, and a bloodstained car seat belt. The prosecution agreed to take the
death penalty off the table and rehome Hilton's own dog, Dandy, if Hilton would lead investigators to her body. Hilton agreed and successfully led investigators to Emerson's body. Hilton claimed he had asked Emerson for her debit card PIN and that when she failed to give him the correct number, he kept her for four days before killing her with a tire iron. Hilton stated he could not bring himself to kill her dog and that when it came to the woman herself, "It was hard ... you gotta remember we had spent several good days together." ==Conviction==
