King County Prosecutors on Wednesday charged a 28-year-old Renton man, whom police consider a person of interest in Sunday morning’s deadly shootings outside the Sports Page Tavern in north Auburn, with one count of unlawful possession of a firearm.

As a convicted felon, Troy L Neal is not allowed to have a gun.

Auburn police had originally charged Neal with reckless endangerment. Dan Donohoe, a spokesman for the prosecutor’s office, said the investigation into that potential offense continues.

Wednesday afternoon marked the 72-hour deadline for prosecutors to officially charge Neal with a crime or to let him go.

“The defendant’s actions are extremely concerning,” prosecutor Greta M. Jibbensmith wrote in charging papers. “He is a convicted felon in possession of a firearm. He admitted to firing off three or four rounds in the crowded parking lot of the Sports Page Tavern during the middle of a brawl.

“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,” Jibbensmith wrote.

Arraignment is April 15 at the Maleng Regional Justice Center in Kent.

According to the King County Medical Examiner, two of the victims, Lorenzo Duncan, 23, and Antaun Greer, 21, died of multiple gunshot wounds. The third, Nicholas Lindsay, 26, died of a single gunshot wound to the torso.

The Auburn Police Department’s Certification for Determination of Probable Cause, which forms the basis for the charge, offers the following account.

As officers were responding to the shooting scene shortly before 2 a.m., various callers were reporting and describing suspects and suspect vehicles peeling out of the parking lot.

According to the police account, callers told police that the shooting suspects may have left in several vehicles, among them a black Impala with a known license plate.

The Kent Police Department later stopped a black Chevrolet Impala with that plate, driven by Neal. According to the police account, as he stepped out of his vehicle, a handgun fell to the ground. When officers asked  if he was armed, according to the account, Neal replied that the gun was inside the car. Police interviewed the two passengers in the vehicle and released them.

According to the police account, Neal told detectives that he had fired his .45 caliber Smith and Wesson handgun three or four times in the Sports Page parking lot before reloading a second magazine into his gun and putting it in the car’s center console.

According to the police account, the gun had one round in the chamber and a seated, fully-loaded magazine. In a soft lunch box behind the console police found a scale and 38 pills — ecstasy and Oxycodone.

According to earlier court papers, Neal 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.

A Superior Court Judge on Monday set Neal’s bail at $250,000.
