I am very sorry to hear about your family's loss. The answer is yes.
Under Oregon's § 30.020:
When the death of a person is caused by the wrongful act or omission of another, the personal representative of the decedent, for the benefit of the decedents surviving spouse, surviving children, surviving parents and other individuals, if any, who under the law of intestate succession of the state of the decedents domicile would be entitled to inherit the personal property of the decedent, and for the benefit of any stepchild or stepparent whether that stepchild or stepparent would be entitled to inherit the personal property of the decedent or not, may maintain an action against the wrongdoer, if the decedent might have maintained an action, had the decedent lived, against the wrongdoer for an injury done by the same act or omission. The action shall be commenced within three years after the injury causing the death of the decedent is discovered or reasonably should have been discovered by the decedent, by the personal representative or by a person for whose benefit the action may be brought under this section if that person is not the wrongdoer. In no case may an action be commenced later than the earliest of:
(a)Three years after the death of the decedent; or
(b)The longest of any other period for commencing an action under a statute of ultimate repose that applies to the act or omission causing the injury, including but not limited to the statutes of ultimate repose...
See HERE for the full statute.
As such, the family may pursue a wrongful death claim provided that there is sufficient evidence to argue that the death was caused by "wrongful act or omission of another."
