"I have concluded no crime can be proven beyond a reasonable doubt", Rees wrote in the July 27, 2011, memo.
The woman went to police more than a week after the incident, but she immediately told her friend and boyfriend about it. Cuban actually chose to speak at length with Portland Police Detective Brendan McGuire, who filed the report, rather than consulting an attorney first.
'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'.
Cuban flatly denied the woman's allegations and provided a prosecutors' report detailing the decision not to file charges. The alleged victim told Willamette Week that she has moved on from the incident, but stands by her story. "I stand behind that report 1,000 percent".
Cuban denied the allegations as well by simply saying, "it didn't happen".
Cuban emailed the Associated Press late Tuesday night, and wrote "It didn't happen".
This news comes a week after Sports Illustrated revealed that there was an ongoing investigation within the Mavericks organization that was described as a "corporate culture rife with misogyny and predatory sexual behaviour".
Portland's Willamette Week published what it said were details from a case that police did not pursue because of a lack of evidence. None said they witnessed an assault. "I haven't thought about it for seven years".
The police report explains that in one of the pictures, she appears uncomfortable.
McGuire also noted the alleged victim's expression: "Her teeth are clenched, eyes wider than the other pictures and brow raised showing a look of surprise and strain". Cuban, who owns the Mavericks, is alleged to have actually slid his finger into her vagina.
Cuban, she said, appeared "very drunk". "In this case have you lied to your attorney in any way?"
The two doctors, both from the George Washington University School of Medicine & Health Sciences in Washington, D.C., reviewed the allegations in the case.
Furthermore, they added, "There is no evidence to corroborate the complainant's statement and there is evidence contradicting the claim".
