AURORA | Police doubled the reward for information on a quadruple shooting that left one man dead outside an Aurora night club early Sunday morning.

Investigators are now offering $4,000 for information about who shot and killed Dejon Williams, 37, and wounded three others around 2 a.m. May 27.

The shooting happened outside the Kasbah Nightclub in parking lot at 15373 E. Sixth Ave., near East Sixth Avenue and Helena Street in Aurora.

When officers arrived, they found four adults who had been shot. All four were taken to local hospitals, where one man died from his injuries, police said.

Names and details on the status of the three wounded people have not been released.

Police said homicide detectives are following up multiple leads and trying to speak to any witness they can, but no arrests have been made.

“Detectives believe that there are other witnesses who have information about this incident or who may be able to identify the suspect. No piece of information, no matter how slight, is considered to be insignificant,” police said in a statement.

Initially police said they believed the shooting stemmed from a fight inside the club. On Friday Aurora police spokesman Officer Bill Hummel said police had not determined what connection there was between the nearby club and the shooting.

Shelton Bouknight, owner of Kasbah, said he reviewed his security footage and there was no fight inside his club before the shooting. Instead, he said the crowd left peacefully at closing time, got in their cars and headed home.

He said he is frustrated that police linked his club to the shooting and doesn’t think there was any connection between Kasbah and the shooting.

Police are asking anyone with information about the incident to call Detective Alton Reed at 303-739-6068. Tipsters can also remain anonymous earn a $4,000 reward by contacting Metro Denver Crime Stoppers at 720-913-7867.
