CARROLLTON — A Texas man accused of raping a 16-year-old girl used social media to lure her to a meeting, abduct her from her school and drive her to a river, where he killed her to keep her from testifying against him, an arrest warrant said.

The man insisted in a jailhouse interview Monday that he only wanted to talk to the teen and prove his innocence but said he was overcome by “demons” once they were face-to-face.
