LaGRANGE — A Troup County grand jury Monday indicted a Newnan man accused of shooting his coworker at the Kia assembly plant in West Point in April.

Gabriel K. Raines, 38, faces charges of aggravated assault and felony firearm possession for allegedly shooting fellow Kia plant employee Gary Swanson, 28, once in the leg on April 21 inside the plant at about 2:45 p.m.

Witnesses told police that after the shooting, Raines calmly walked outside the plant and sat on a curb as he waited for police to take him into custody. Two individuals convinced Raines to hand over the gun, according to police.

Police have not released a motive in the shooting, but in May, West Point police detective Shannon Bavaro testified in magistrate court that Raines told supervisors at the plant his coworkers were harassing him on the job. Bavaro told the court she wasn’t sure if Swanson was specifically named on the harassment complaints.

Investigators at the scene of the shooting recovered the handgun allegedly used by Raines; it was purchased in late 2014 at a Newnan pawn shop, according to Bavaro’s testimony. Investigators also found prescription medication in Raines’ car, but Bavaro was unable to specifically identify it on the witness stand.

Raines had a history of mental illness, according to courtroom testimony, and in the days prior to the shooting had been on medical leave for mental health reasons. A psychiatrist cleared him to return to work one or two days prior to the shooting, Bavaro testified in May.

Barry Hazen, an Atlanta-based attorney who represented Raines in magistrate court, questioned Bavaro in court as to whether or not she knew about Raines’ mental health history.

“Are you aware of other kinds of complaints that Mr. Raines made, such as people implanting things in his head and listening to his thoughts?” Hazen asked Bavaro in court.

“I am aware of that now,” Bavaro testified. “We received a report from Newnan police and also from his wife that night. She advised me that he was making those kinds of complaints. Newnan police has a report that indicates he was making those kind of complaints.”

It is unclear how Raines was allegedly able to bring a gun into the facility. Randy Jackson, a Kia Motors Manufacturing Georgia senior vice president, told the Daily News in May that the plant has taken steps to address security concerns.

Raines is being held without bond at the Troup County Jail on Sam Walker Drive pending an arraignment in Troup County Superior Court; that arraignment date has not yet been set.
