The GBI says evidence found at a Hawkinsville site last week is human remains, and they will run tests to show whether they are the remains of Jmaal Keyes.
The remains were found near the home of 17-year-old Robert Rolinson.
He's accused of killing Keyes, a Cochran college student.
Keyes went missing around April 25 from the campus of Middle Georgia State College in Cochran.
Last week, Rolinson, a dual enrollment high school student attending classes on campus, was charged with killing him.
So far, searchers have failed to find Keyes' body.
Investigators have not revealed how they think Keyes died or why, and have not described the relationship between the two students.
On Monday, a GBI spokesman said they found possible evidence in the case somewhere on a 30-acre site near a home owned by Rolinson's family.
Todd Lowery of the GBI Eastman office said the evidence was sent to the crime lab, and said "we're not prepared to say we've found his body."
