James Brown was a seaman in the United States. In 1967, Brown was discovered on his fishing boat on his way to Labrador. He had drained another sailor of his blood.
Brown was arrested and returned to Boston, where he was sentenced to life in prison.
While in prison, Brown killed at least two more people and drank their blood.
After the second killing while in jail, Brown was moved to the National Asylum in Washington, D.C., where he remained in a padded cell until he died.
