Investigators found insufficient evidence that the 26-year-old football player attacked Supriya Harris.
"Our investigation is complete," said Las Vegas police Officer Barbara , a department spokeswoman. "I don't think the time passage was a factor here. We contacted the victim, the accused and witnesses. There's insufficient evidence to go forward with the case."
Copies of the complaint from Harris were plastered all over the Internet and included allegations that Jackson had thrown her to the ground repeatedly and flung her against a door.
Jackson issued a statement calling these charges "untrue" and "hurtful."
