LAS VEGAS — The ex-husband and children of a Henderson city judge who died last year with the powerful opioid fentanyl in her system have filed a wrongful death lawsuit against a doctor accused in another case of illegally distributing the drug.

The lawsuit against Dr. Steven Holper was filed Feb. 27 in Nevada state court by Diana Hampton’s ex-husband, Henderson police Lt. Scott Hampton, and her two children, ages 14 and 12.

A message left Wednesday at Holper’s medical office was not immediately returned.

Holper was arrested last month on federal charges of unlawful distribution of fentanyl and providing a false statement about a health benefit program.

The Clark County coroner ruled in April 2016 that Diana Hampton died of severe sepsis following an arm infection, and that fentanyl in her system contributed to her death.

The Las Vegas Review-Journal reports the wrongful death case alleges that Holper improperly provided Hampton with the painkiller.
