A computer forensics expert testified Thursday about text messages to and from one of two Steubenville, Ohio, football players accused of raping a drunken teenage girl.
The testimony from Joann Gibb of the Ohio Bureau of Criminal Investigation came on the second day of a case that focuses heavily on texts, cell phone images and social media posts surrounding the alleged sexual abuse of the 16-year-old girl in August 2012.
Two Steubenville high school football players -- Trent Mays, 17, and Ma'lik Richmond, 16 -- are accused of sexually assaulting the girl during a series of end-of-summer parties in August.
The teens are charged with rape. Mays also charged with illegal use of a minor in nudity-oriented material. Defense attorneys say the two are innocent.
According to prosecutors, Richmond and Mays each penetrated the victim's vagina with their fingers, an act that constitutes rape under Ohio law.
Prosecutors contend the text messages between Mays and his friends and classmates on August 12 detail a night of heavy drinking and the sexual abuse of the girl.
The defense questioned the validity of the messages, with Mays' attorney asking Gibb whether she could be absolutely sure the messages were from his client.
"I can't put a person behind a cell phone," she said.
Some of the messages were between Mays and the alleged victim.
In one message she asks what happened "last night."
"And don't lie about anything. I need to know the truth. People keep asking. Idk (I don't know) what to say," the message said, according to Gibb.
Mays responded that "nothing happened last night," telling her in the message she performed a sex act on him, Gibb testified.
CNN is not identifying the girl in line with its policy of not identifying the alleged victims of sexual assault. CNN is also not identifying minors who testify at the trial but is identifying Mays and Richmond, whose names have been used by court officials and their attorneys and in multiple media accounts.
Some of the messages from Mays, according to Gibb, say he had sex with the girl while in others he say the girl performed a sex act on him.
One message asked Mays: " Did u do it?"
He responded, according to Gibb: "No, lol. She could barely move."
Another message to Mays from still another friend asked "how dead is she?"
Mays responded, according to Gibb, "not at all, she's looking for her phone."
Still another graphic message from Mays to a friend appeared to detail his anger over being accused of rape.
"I'm pissed all I got was a hand job, though. I should have raped since everyone thinks I did," the message said, according to Gibb.
The testimony Thursday showed just how much of the case rests on the prosecution's stance that the alleged victim was too drunk to consent to sex.
'Stumbling and slurring'
One of the witnesses, a college freshman who described himself as a friend of Mays and Richmond's cousin, testified he saw the alleged victim "stumbling and slurring her words" at the first of a series of parties that night.
The next day, he testified he texted Mays from a friend's phone asking about the alleged rape and told him he could go to jail for that.
