How does he get his hands down her jeans and penetrate her before she jumps away? That never happened.

“He then moved his hand down until it was on her buttocks,” read the Portland police detective’s summary of the alleged victim’s statement, obtained by Willamette Week. “Cuban then pushed his hand down the back of her jeans and inside her underwear where he cupped his hand over her groin area and inserted the tip of his finger into her vagina.”
The woman gave seven cell phone photos from the evening to police, but the bureau declined to release them to Willamette Week. Two of the photos were described as notable in the police report:
In both images, Cuban’s right shoulder is lowered and he appears to be stretching to reach his arm down. In one of the pictures, his arm can be seen behind [the alleged victim] and it appears Cuban is reaching down toward her buttocks.

The way Cuban touched some of the women struck White as inappropriate because his hands moved well below the middle of their backs, he said.
"He was, like, really kind of gropey toward them," White said. "It just wasn't how you'd normally pose in a picture with someone."
