What authorities describe as a homeless camp on the water has sunk.

KOMO-TV reports the floating camp was made up of three boats rafted together and tied up illegally to a fishing net piling belonging to the Duwamish Tribe.

Two boats sank last week in the Duwamish Waterway, while a third remained afloat.

How the boats sank is still being investigated by the Port of Seattle. They were outside the federal waterway that’s the responsibility of the Coast Guard — so it’s under Port of Seattle jurisdiction.

Officials say the Coast Guard pumped out fuel and removed hazardous chemicals that were found on board.

On Wednesday, a salvage crew removed both boats.
