Authorities are still searching for a missing teenager who they believe was murdered.
Jmaal Keyes, 19, disappeared last month while attending Middle Georgia State College south of Macon.
Investigators with the Georgia Bureau of Investigation scanned the Ocmulgee River in Pulaski County all day Friday, looking for Keyes, a recent graduate of Hiram High School in Paulding County.
The victim's girlfriend, Ronique Green, said she's done all she could to find Keyes, posting messages on social media sites, and even calling people he went to school with, including Keyes'
classmate, who is charged in his murder.
Green said Robert Rolison admitted to being with Keyes the day he was reported missing, but his story just didn't add up.
"I knew he was lying, because he said Jmaal went back to his room. But on the video surveillance camera from the school, they said he didn't go back," Green told Channel 2's Ashley Swann.
Green said she wants closure for herself and for Keyes' family.
"This is somebody's brother. This is somebody's son, and he didn't mess with anybody, so that's why it's just so devastating. My whole life is altered," Green said.

GBI said the evidence was found in a "ground, as opposed to water" search in Pulaski County. It was found in a search which began Friday and stretched into the wee hours of Saturday.
The search for Keyes is ongoing.
