One witness, a 17-year-old, testified the victim told her she believed she had been drugged the night of the assault, an allegation the witness said she did not believe because the girl "lies about things."
A hospital test on the victim for drugging came back negative, testimony revealed.
The teen witnesses, who described themselves as classmates and former best friends of the girl, told the court they saw the victim drinking. She drank at least four shots of vodka, two beers and some of a slushy mixed with vodka, a 16-year-old witness said.
The defense attempted to question the two teens about the victim's history, but the judge did not allow most of the line of questioning. Ohio, like most states, has a rape shield law that limits the amount of information of an alleged victim's past that can be explored in court.
The 17-year-old witness said she picked the victim up the next morning from someone's home and asked her what happened.
In the car, the victim said, "We didn't have sex, I swear. I don't know what happened. I don't remember," the teen testified.
On Friday, three teens, all self-described friends of the co-defendants, testified that they saw Mays and Richmond engage in sexual contact with the girl. All three have been granted immunity from prosecution.
One of the witnesses -- identified as a 17-year-old Steubenville football player and wrestler -- testified that he used his cell phone to record Mays putting his fingers inside the girl's vagina during a drive from one party to another. He said he deleted the video the next morning when he realized it was wrong.
The teen also testified that Mays later attempted to have the girl perform a sex act on him in the basement of a home.
"She didn't really respond to it," he said.
