A man died in a shooting at an art gathering in Seattle’s Pioneer Square neighborhood late Thursday, according to police.

Taking place at the rooftop of a building that’s part of the RailSpur development, the gathering was meant to kick off several days of art exhibits and celebrations across the city in conjunction with the Seattle Art Fair happening at the nearby Lumen Field Event Center.

Shortly before 9:30 p.m. Thursday, officers responded to a report of shots fired on the rooftop of the building at 419 Occidental Ave. S., according to police. They found a 30-year-old man who had been shot, the Seattle Police Department said in an online blotter post.

Despite lifesaving measures from police and fire, the man died, police said.

Police found a second man on the street with a non-life-threatening injury from a tile shattered during the shooting.

Police said it was not clear what led to the shooting and they have not identified any suspects.
