The latest evidence for this conclusion is the decision of the Rhode Island Supreme Court in Volpe v. Gallagher, a case that raised the issue of whether a parent can be held liable for the actions of an adult son with mental illness (1). As in many cases involving questions of third-party liability, the facts are tragic. Sara Gallagher, the defendant in the case, owned a small house in North Providence, where she lived with her 34-year-old son, James Gallagher. In the words of the court, James Gallagher was "[a] jobless and practically friendless loner who was plagued by hallucinations, imaginary conversants, and a paranoid distrust of others." He lived in the basement of the house, where he kept, apparently for many years, a shotgun, a pistol, and assorted ammunition.
