The mother of a 15-year-old girl who was killed in a mass shooting at a Kentucky high school says her daughter called during the bloodshed — but the mortally wounded sophomore couldn’t speak.

Secret Holt said she relentlessly tried to reach her daughter Bailey over the phone when she was first alerted to the shooting at Marshall County High School on Tuesday.

“We tried and tried to call her and she didn’t answer,” Secret Holt told WKRN. “It’s not like her to not answer or text back.”

The teen eventually returned her mother’s call, but the girl never spoke over the line.

“She called me and all I could hear was voices, chaos in the background,” Holt told the station. “She couldn’t say anything and I tried to call her name over and over and over and she never responded. We rushed to the high school, and they wouldn’t let us get through.”

The mother later learned her daughter was one of two victims killed after she rushed to another school to wait for Bailey to be ushered off one of several buses used to transport students away from the bloody scene. But the teen never arrived.

“We waited and waited for her to get off the buses and she never did,” Secret Holt said. “The principal at North Marshal came and got me, and took us outside and we got in a cop car and they took us to the fire department and told us what had happened.”

Authorities say Bailey and another student, Preston Ryan Cope, were killed when a 15-year-old with a gun opened fire inside the building.

Eighteen others, ranging in age from 14 to 18, also were injured. Three victims were listed in stable condition Thursday, while one remained in critical but stable condition, officials said.

The suspected shooter, who was not identified, was expected to face two counts of murder and multiple assault charges. Prosecutors say he will be tried as an adult and is expected to appear before a grand jury on Feb. 13.

Bailey’s mother said that while her daughter was young, her life made a lasting impression.

“She helped others,” Secret Holt said. “She was just so kindhearted and the most amazing kid anybody could ever ask for. Her smile could light up the room.”

And she said she’ll pray for the alleged shooter, despite her struggle.

“It’s just so hard to believe that somebody in a split second could take two lives and injure so many in just a short amount of time,” Secret Holt said. “I don’t know if I can go to court and see him. I just don’t know if I can, but I want him to pay for everything he’s done. I also want to pray for him too, because I know he’s probably having a hard time too, but he took our baby. He still took my baby away from me.”
