SEATTLE -- Police have identified a man wanted in connection with the death of a 60-year-old man who died after being assaulted during a dispute at a traffic circle last week.

Investigators are looking for Brian Keith Brown, 28, who has been charged with second-degree murder in the death of James Paroline.

Paroline ran into trouble July 9 while watering plants in the roundabout at South Cooper Street and 61st Avenue South. He had set up cones to keep cars from driving over his hose while he watered, and his cones were causing traffic to back up.

Three young women in a car near the intersection confronted Paroline and demanded that he move the cones. When he refused, one of the girls got out of the car and began moving the cones herself.

According to charging documents, a neighbor videotaped the disturbance and the video shows Paroline trying to ignore the girls and continue watering.

"The girls were yelling and screaming at Paroline, and one threw a water jug at him," the documents said. "Though the girls could be heard yelling that Paroline squirted them with water, and that he had assaulted one of them, that cannot be seen on the video. What can be seen are the girls circling ParolIne and continually screaming, and Paroline walking away from them and attempting to continue watering the traffic circle."

However, another cell phone video clip obtained by KOMO News, which captured the beginnings of the incident prior to the fatal attack from a farther angle, does show Paroline briefly spraying one of the girls with the hose, though he is not seen assaulting her in any way. Police have not reviewed this video clip.

Charging documents said about 20 minutes later another vehicle pulled up to the scene and Brown got out, walked up to Paroline and punched him in the face.

The blow knocked Paroline to the ground and he cracked his skull on the pavement. He fell into a coma and died at a hospital the next day.

When questioned by police, the girls involved in the initial dispute denied knowing Brown, but a detective wrote they later admitted that Brown was the boyfriend of one of their sisters.

Records indicate Brown has an extensive criminal history which includes nine prior convictions, two of which were for felony assault.

"This is somebody we'd very much like to take into custody," said Officer Mark Jamieson.

Friends said the victim, who went by the nickname "Jage," took great pride in maintaining the traffic circle, which is right next to his home.

Paroline was a Vietnam veteran who survived the war only to be critically injured and left to die in his own hometown, friends said.

"It's hard to describe. It's something you wouldn't wish on your most enemy," said one friend, Chuck Benson. "There's no cause for it. ... It was just nonsensical."

"They could have gone around the cones and let him finish his job," said Irene Lyle.

The former lieutenant and mortgage broker loved gardening and taking care of his two dogs, Joe and Happy.

"He raised flowers, and shortly after we moved in, he came by and said if we wanted any flowers for our yard, he'd be happy to share with us," said neighbor Diane Larkin. "Just seemed like a very nice man."

"There are individuals who stand up for their community, their neighborhood, their blocks. He was one of those guys. I didn't know him personally, but I feel a kinship to him," said neighbor Kevin Barth.

Anyone with information about Brown's whereabouts is asked to call 911.
