Nancy Bernstein, the second ex-wife of slain Las Vegas attorney Dennis Prince, has filed a civil lawsuit targeting the Houston family and their former law firm. The complaint alleges the family had knowledge of and failed to act on threats made by Dylan Houston prior to the April 2024 shooting at the Summerlin law office that left Dennis Prince and his girlfriend Ashley Prince dead.

Why it matters

This case represents the latest civil lawsuit stemming from the high-profile Summerlin shooting, which has already resulted in a wrongful death complaint filed by the victims' family. The new lawsuit could force the release of additional documents and testimony that may uncover further details about the incident and the actions or inactions of the Houston family members.

The details

Bernstein's lawsuit claims that during the deposition where the shooting occurred, Katherine Houston left the room and later took actions the complaint characterizes as concealment and self-interest. The lawsuit also alleges that Dylan Houston sent hostile communications to his ex-wife Ashley Prince, including statements like "I don't want to see you unless you're in a casket" and "I will chisel you down to a weaker and worthless sack of bones." However, the Las Vegas Metropolitan Police Department's final homicide report states that investigators found no evidence Joseph Houston informed anyone of a plan to kill Dennis and Ashley Prince, concluding he acted alone.

  • The shooting occurred on April 8, 2024.
  • Bernstein filed the civil lawsuit in March 2026.
  • In February 2025, Ashley Prince's parents filed a separate wrongful-death complaint.
