Experience

Representative Matters

  • In 2019 and 2020, Duffy recovered the policy limits of the defendants’ liability insurance coverage in several personal injury cases. Those cases include an elderly couple injured in a Monterey County car crash (seven-figure settlement), a woman who suffered a concussion in a Santa Barbara County car crash (six-figure settlement), and a woman who suffered broken ribs in a San Mateo County car crash (six-figure settlement).
  • In 2019, John Thyken and Duffy recovered over $1.5 million for three small business owners displaced by a fire that started when an unlicensed driver crashed into the building where they leased space for their businesses. After three years of litigation with insurance companies for the landlord, the neighboring property owner, and the driver, the CPM team prevailed and obtained a substantial recovery for the small business owners.
  • In 2018, Anne Marie Murphy and Duffy won a seven-figure jury verdict in San Mateo County on behalf of an international businessman who suffered over $1 million dollars in real estate losses caused by his local real estate investment partners. After a three-week trial, the jury found that the local partners had breached their partnership agreement with CPM’s client, and the jury rejected the defense cross-complaint seeking damages against the plaintiff—a complete victory for CPM’s client.
  • In 2017, Duffy prosecuted three international drug traffickers in a three-month jury trial. The trial was the culmination of a multi-year DEA investigation which resulted in the seizure of approximately $4 million worth of cocaine, methamphetamine, and United States currency.
  • In late 2016 and early 2017, Duffy convicted a domestic abuser of first-degree murder, a jealous ex-boyfriend of second-degree murder, and a scorned lover of conspiracy to murder in three separate jury trials.
