The University of Illinois is closing its investigation into the sexual assault accusations made against basketball player Terrence Shannon Jr., according to ESPN's Shwetha Surendran.

The school's director of the office for student conflict resolution, Robert Wilczynski, wrote to Shannon on April 5, noting that the school didn't have sufficient evidence to prove there was a violation of the student code.

Per that letter, the school wasn't given "access to the complainant, the complainant's witness." Additionally, "the complete Lawrence Police Department file was not available to the investigator."

Shannon, 23, was arrested and charged with rape, sexual intercourse without consent and use of force on Dec. 28 after a woman accused him of digitally penetrating her without consent in September at a bar in Lawrence, Kansas.

He posted a $50,000 bond and one of his attorneys, Mark P. Sutter, said Shannon has maintained his innocence "from the beginning" and has "cooperated with law enforcement throughout the investigation."

He is still facing criminal charges in Kansas, with a preliminary hearing slated for May 10.

Shannon was suspended indefinitely from the team in January but sued both the school and its president, Timothy Killeen, and also filed for an injunction. A federal judge granted him a temporary restraining order in January, allowing him to return to the court. He has since dropped the lawsuit.

He then helped lead the Illini to the Elite Eight in the NCAA men's tournament. An April 10 post on social media suggested he will declare for the 2024 NBA draft:

Robert Lang, Shannon's attorney, said the senior guard "fully cooperated with the university's investigation, and the university did as thorough of an investigation as possible that spanned several weeks."
