Police have issued an arrest warrant for Ja'mari Alexander-Jones , who is believed to be driving a white Nissan Maxima with Washington license plate AHZ1672. Bellevue police describe Jones as 5 feet 8 inches tall weighing 140 pounds and say Jones should be considered armed and dangerous.
Jones is one of three teens who beat to death Ed McMichael -- better known as "Tuba Man" in October of 2008.
Jones was sentenced to less than a year in juvenile detention on a first-degree manslaughter charge in that case.
The shooting broke out just after 1 a.m. at Munchbar at Bellevue Square, said Carla Iafrate, a spokeswoman for the Bellevue Police Department.
Police officers were outside the bar when gunfire erupted because a large crowd had gathered there, she said.
More than 600 people were inside the venue at the time of the shooting to watch the Seattle Seahawks victory over the San Francisco 49ers and celebrate afterward.
"It was crazy, I just heard some shots and I just got down," said witness Dejuan Lofton. "It was just wild."
Investigators say the gunfire started after several fights broke out.
"There were several incidents and altercations that were going on inside the Munch bar that possibly led up to the shooting," Iafrate said.
Ja'mari Alexander-JonesSeattle Seahawks coach Pete Carroll said several players were at Munchbar following the team's victory, but none were injured.
"From what we know our guys were in a separate area and nobody was involved at all," Carroll said during a Monday news conference. "It was an awful thing that happened.".
Cornelius Bomet says he saw some of the Seahawks players taking cover nearby.
"You have professional football players, they're all in their little cubby. They're on the floor," he said.
Other celebrities were on hand as well. Reality TV star Aubrey O'Day tweeted a photo from the crime scene and part of her Tweet read: "Everyone was on the floor. People got shot."
Plenty of people were terrified.
"It's a whirlwind," Lofton said. "I'm still shaking to my knees."
Some witnesses thought the shooting may have started as an argument over a woman, but Bellevue police are still looking into the motive. A police source tells KOMO News they are investigating possible connections between this and a shooting at the Seattle nightclub Citrus earlier this year.
The wounded victim was in stable condition at Harborview Medical Center receiving treatment for a gun shot wound to his hand.
Meanwhile, police say there were several varying descriptions of the shooter, so they will rely on surveillance video for clues.
