A 20-year-old woman pleaded guilty Friday morning to falsely reporting a crime in connection with an April 2010 incident that prompted police to lock down Kansas University’s largest residence hall as they searched for a reported gunman.

The crime was later discovered to be a hoax.

Douglas County prosecutors said District Judge Sally Pokorny sentenced Kori B. Williams to serve six months of unsupervised probation for the misdemeanor conviction.

Samuel L. Moore of Kansas City, Kan., had pleaded guilty to obstruction in the case last June and received a one-year probation sentence for lying to KU Public Safety officers.

On April 30, police were investigating a reported domestic incident at McCollum Hall after a resident heard a male voice in the next room say, “Where’s my gun?”

Prosecutors said Williams, a McCollum Hall resident at the time, and Moore were the ones arguing, but they made up a story, saying another man attacked Williams. The couple fabricated the story to prevent Moore, who was banned from the dorm, from getting in trouble.

The event led to a lockdown of the dorm and a large manhunt before Moore later turned himself in to police.

Williams is no longer a KU student and currently attends school and works in the St. Louis area, prosecutors said. If she commits any other crimes in the next six months, Pokorny could decide to revoke her probation and order her serve 30 days in jail for the Douglas County conviction.
