LOUISVILLE, Ky. >> An unidentified suspect fired a gun into a crowd of hundreds in a Kentucky park, leaving two people dead and four wounded Saturday night, police said.

Police were called around 9 p.m. to Chickasaw Park in Louisville, authorities said.

“Hundreds of people were in the park at the time of the shooting, when someone started shooting into the crowd, hitting at least six people,” Louisville Metro Police Department Deputy Chief Paul Humphrey said.

There were no suspects in custody immediately after the shooting and police asked anyone with information to contact investigators.

“As of right now we have no witnesses,” Humphrey said.

“This has been an unspeakable week of tragedy for our city,” Mayor Craig Greenberg said at the scene Saturday night, referring to a shooting on Monday in which a gunman killed five Louisville bank employees while livestreaming the attack on Instagram.

“On Monday, we lost five of our fellow citizens to a horrific act of workplace gun violence,” Greenberg said. “And now, five days later, we’re at another scene of a reckless act of gun violence.”

Police have not publicly identified the deceased other than to say they were both adult males. The four wounded included one adult female and three adult males, according to an email from police spokesperson Alicia Smiley. As of Sunday morning, one of the injured had been released from the hospital. One person who was admitted in critical condition was listed as critical but stable on Sunday.

Police were not aware of any special event taking place at the park on Saturday night, and Smiley said the crowd was not unusual considering the nice weather.
