Douglas County prosecutors have charged a 20-year-old woman with falsely reporting a crime in connection with an April incident that led to chaos at Kansas University’s largest residence hall.

Kori B. Williams, of St. Louis, pleaded not guilty to the misdemeanor charge Tuesday in Douglas County District Court.

Samuel L. Moore, 21, of Kansas City, Kan., has already pleaded guilty to obstruction in the case and received one year of probation for lying to KU Public Safety officers. On April 30, police were investigating a reported domestic incident at McCollum Hall after a resident next door heard a male voice say, “Where’s my gun?”

During Moore’s case, prosecutors say Williams, a McCollum Hall resident at the time, and Moore were the ones who were arguing. Authorities accuse the two of making up a story about another man who attacked her.

It was aimed at keeping Moore, who was banned from the dorm, out of trouble, but it set off a lockdown of the dorm and a large manhunt. Moore later turned himself in to police.

Williams turned herself in earlier this month after prosecutors issued a warrant for her arrest in May. She is free on $500 bond.

KU officials in April said she would face student housing and nonacademic disciplinary hearings. Her next court appearance is scheduled for Aug. 2.
