Davis continued to deny the allegations at his trial.
"She lied," Davis said on the stand, according to Dallas television station KTVT. "She ruined my life. She took everything from me, everything I work so hard to get. She took it."
In the days before he killed Gray, Davis called and sent her text messages pretending to be a boy and asking her questions about the sexual assault case. The day of the killing, Gray got a text message saying her new friend was outside her school to surprise her.
Davis' defense attorneys argued he was trying to do his own investigation after police did not. But prosecutors scoffed at that notion.
"You know it, I know it and he knows it," prosecutor Russell Wilson told jurors, according to The Dallas Morning News.
