Charlottesville Police Chief Timothy Longo said Monday that his department was “not able to conclude to any substantive degree” that the University of Virginia gang-rape described in a Nov. 19, 2014 Rolling Stone article actually happened.

Longo disputed several points made in the article, including the accuser Jackie’s claim that she received no help after reporting the incident to campus officials. The police chief said that police spoke with Jackie in May 2014, after she claimed to school officials she suffered a second attack.
