COLUMBIA — Missouri senior guard Michael Dixon Jr. was accused of sexual assault Aug. 20, according to a report by the Kansas City Star.
Dixon has been suspended from the basketball team since October.
The case was closed Nov. 16 because the Boone County Prosecuting Attorney's Office said there was insufficient evidence to charge Dixon.
Boone County Assistant Prosecutor Tracy Gonzalez said Tuesday evening that she made the decision not to pursue charges against Dixon. She said that after a thorough investigation by the Columbia Police Department, there was not enough evidence to prove guilt beyond a reasonable doubt in court.
Gonzalez would not go in to the specifics of the evidence.
The allegations of sexual assault first came to light on Twitter early Saturday after a woman tweeted she was sexually assaulted by Dixon, in response to former Missouri player Kim English's tweets questioning Dixon's suspension from the basketball team.
English's tweet, which has been removed, said "The Univ of Missouri 'student board' is a joke. Acting and making a decision without having actual facts. University should be ashamed!".
He later tweeted, "Michael has handled this situation w/ nothing but poise, class and professionalism. Would be awesome if his University would do the same."
A later post read, "Thank God we have an AMAZING chancellor who I trust will make the right decision soon. And do what's right by reinstating Michael Dixon Jr."
English currently plays for the Detroit Pistons.
The woman responded with a tweet saying, "Yes, I said it. Michael Dixon sexually assaulted me. That's why he is suspended. You can call me names, but I know what he did."
Her tweets were removed shortly afterward.
The student board English mentioned is MU's Student Conduct Committee. The committee is composed of MU faculty members; it decides cases using MU's Standard of Conduct.
If the committee removes Dixon from the university, the M-Book says Dixon can appeal the ruling through MU Chancellor Brady Deaton or someone he designates to determine the appeal. The decision made in the appeal is final, unless "it is to remand the matter for further proceedings," according to the M-Book.
A student going through the appeals process can stay in school until a decision is made according to the M-Book, MU's guide to student conduct.
Dixon has been practicing and traveling with the team.
Missouri coach Frank Haith has declined to comment on Dixon's suspension throughout the season, stating originally that it was because of a violation of team policy.
Calls to Dave Reiter, director of strategic communications for the Missouri men's basketball team, were not returned Tuesday evening.
