An Atlanta Police detective testified during a preliminary hearing for one of the two accused killers of Alexis Crawford that both admitted at least parts of their roles in the murder while under questioning.

Barron Brantley, the man arrested in connection with Crawford's murder who is the boyfriend of her roommate, admitted to Det. Michael Young testified that they were both involved. 

"He admitted to choking Alexis, Ms. Crawford, and while he was choking Ms. Crawford, Jordyn Jones put a plastic bag over her head," the detective testified.

Detective Young testified that Jones first tried to tell police she was in her house the entire night of Crawford's death. She said that she did not leave the house until the next morning, but later admitted that she had lied after she was confronted with surveillance footage from her apartment complex's parking deck that showed her at 3:11 a.m. that morning backing her car up to a door off-camera for six or seven minutes, then being seen leaving the complex at 3:17 a.m. and then returning at 4:09 a.m.

"She finally stated Barron Brantley was inside the house with her and her and Alexis got into a fight and during that fight, Barron Brantley came outside of the bedroom and choked Alexis," Young said.

Police say that they believe that the incident may be related to a sexual assault Crawford reported to police Oct. 27. Brantley was the suspect in the incident, which allegedly happened at the apartment Crawford shared with Jones. All three were drinking at the time. Crawford had claimed that she blacked out and that Brantley assaulted her in her sleep. She was afraid to stay in her own room and resorted to sleeping on the living room couch.

Jones told police she saw Crawford around midnight before going to bed, a police report said. Crawford was not in the apartment the next morning when the roommate left for class, and the front door was locked with a deadbolt, per CNN.

"The mood has been very hard. A lot of students have been trying to take into account what happened and just find answers to things we can't find answers to," said student government president Levon Campbell per MSN News.

Brantley's arrest reportedly violated his bond conditions for a prior arrest on charges of theft, battery, and cruelty to children, according to the report.
