Authorities in Washington state have released the name of the fourth victim in a standoff that left five people dead, including the gunman.

Mason County Coroner Wes Stockwell says 68-year-old Donna Reed was among the four people whose bodies were found in a chicken coop after Friday's standoff.

The standoff began after David Wayne Campbell called a sheriff's office supervisor Friday morning to say he had done something bad and was suicidal. After hours of negotiations, police tried to flush Campbell out using tear gas. They say that's when he stepped outside and killed himself.

It's unclear how Reed and Campbell knew each other. Also killed in the standoff were Campbell's wife of six years, 49-year-old Lana J. Carlson, and her teenage sons, Quinn and Tory Carlson.
