A shooting in a Cincinnati nightclub left 15 people wounded, one of them fatally, early on Sunday morning.
The number of victims could rise, however, because people were traveling to hospitals on their own, Cincinnati police Capt. Kim Williams said.
NBC affiliate WLWT reported that police officers outside the club heard gunshots around 1 a.m., as the Cameo Night Club was closing.
Assistant Police Chief Paul Neudigate has tweeted that there was "only one reported shooter," and that police are "still investigating if others [are] involved."
