Work continues on resolving who did what and when in connection with the shootings that killed three people outside the Sports Page Tavern in Auburn on March 31.

But given the chaotic scene described in court papers and the number of people involved, sorting out who did what and when has slowed progress on the investigation.

No charges have yet been filed.

“The case remains under investigation by the Auburn Police Department in conjunction with our Homicide Unit,” said Ian Goodhew, a spokesman for the King County Prosecutor’s office.

Killed that morning were Lorenzo Duncan, 23, Antaun Greer, 21 and Nicholas Lindsay, 26.

Within days King County Prosecutors charged 28-year-old Troy L Neal of Renton, whom police still consider a person of interest in the deadly shootings, with one count of unlawful possession of a firearm. As a convicted felon, Neal was not allowed to have a gun.

According to court papers, Neal later told detectives that shortly before 2 a.m., he saw several men fighting on the parking lot outside the tavern, one of whom he recognized as his friend, Lindsay.

After he witnessed a man whom he didn’t know shoot Lindsay, Neal told detectives, he retrieved his own pistol and fired five rounds toward the shooter and the surrounding crowd. Neal admitted to detectives that he had been in possession of a .45 caliber handgun.

Neal was convicted in 2005 of possessing a controlled substance without a prescription and for controlled substance felony conspiracy.

“Three people are dead, and one person is injured. The defendant’s actions endangered the lives of all that were present. There is an ongoing investigation to determine the full extent of the defendant’s involvement with the brawl,” prosecuting attorney Greta Jibbensmith wrote in court papers.
