The local sheriff, Barrant Van Ness, stated in a newspaper editorial published in the
San Francisco Bulletin a few days after the massacre that the motive was revenge for
cattle rustling. Ranchers in the inland valleys claimed as much as one-eighth of their cattle had been stolen or slaughtered by Indians over the previous year and one rancher, James C. Ellison, was killed while pursuing suspected rustlers in May 1859. The area where the ranches were located was occupied by the
Nongatl tribe, not the Wiyot, so the victims of the massacre would not have been responsible for any rustling. Van Ness ended his written statement by saying he did not excuse the killers for their deeds. Major
Gabriel J. Rains, Commanding Officer of
Fort Humboldt at the time, reported to his commanding officer that a local group of vigilantes had resolved to "kill every peaceable Indian - man, woman, and child". The vigilantes, calling themselves the
Humboldt Volunteers, Second Brigade, had been formed in early February 1860 in the inland town of
Hydesville, one of the ranching communities in the Nongatl area. They spent most of February "in the field" attacking Indians along the Eel River. A petition had been sent to California Governor
John G. Downey asking that the
Humboldt Volunteers be mustered into service and given regular pay. Downey refused the petition, stating that the U.S. Army was sending an additional Company of Regulars to Fort Humboldt. Despite condemnation of the attack in the press outside Humboldt County, no one was ever prosecuted for the murders. ==Aftermath and present day==
