A hospital spokeswoman says three people are improving after being wounded by gunfire that left two others dead at a homeless encampment in Seattle.

Susan Gregg at Harborview Medical Center says the two women and one male are now in serious condition in the intensive care unit.

Police say they have not arrested anyone in the Tuesday night shooting at the encampment known as "The Jungle."

Officers are searching for two people they want to talk to about the case.
