SEATTLE — Seattle police are investigating a homicide after a man was found dead Saturday morning at a business in the city’s Lake City neighborhood, authorities said.

Officers responded to the 8500 block of Lake City Way Northeast after employees arriving to open the Growler Guys, a beer garden and restaurant, discovered a deceased man inside around 9 a.m. Saturday, Seattle Police Chief Shon Barnes said at the scene.

The man, who police confirmed to be an employee in his early 20s, appeared to have died from gunshot wounds, Barnes said.

Seattle Fire Department personnel pronounced him dead.

Dozens of friends and family members of the young victim spent hours on the scene Saturday, and many were visibly overcome with emotion.

Kelly Dole, owner of the Growler Guys, described the victim as a warm, light-hearted young man.

“He was the type of friend that everybody wanted to have,” Dole said. “His group of friends, which includes my son, are really going to miss him. They’re about as tight as a group of young men can be.”

The victim had been working at the business the night before; however, Seattle police have not confirmed when the shooting happened or what may have led up to it.

“When we have things like this, we have to reevaluate what we could’ve done better,” Chief Barnes said. “How can we make sure that we’re doing everything in our power to bring justice to this family, because quite frankly, they deserve it.”

Detectives are focusing their investigation on the business and were processing the scene for evidence Saturday. Officers, investigators, chaplains, and support services were present.

The restaurant’s owners are cooperating with police, Barnes said. Dole was emotional while speaking with KOMO News about how the tragic shooting has shaken his neighborhood business.

“He always had a smile; he was so buoyant, you could never get him down,” Dole talked about the victim. “The world lost someone important today.”

Authorities said residents can expect an increased police presence in the area as the investigation continues and in the coming days.

There is no suspect information at this time, and police did not make any arrests. The circumstances leading up to the killing are under investigation.

Anyone with information is asked to call the SPD Violent Crimes Tip Line at 206-233-5000.

The killing marks Seattle’s 12th homicide of the year, according to Barnes.
