NH v. Victor Rivera: Bad Breakup Murder Trial

Posted at 7:57 AM, March 10, 2025 and last updated 12:17 PM, March 10, 2025

NASHUA, N.H. (Court TV) — A New Hampshire man will spend the rest of his life in prison after a jury found him guilty of fatally shooting two people.

In January, a jury convicted Victor Rivera of two counts of second-degree murder for the deaths of Patricia Swett and Matthew Champagne. On March 10, Judge Jacki Smith sentenced Rivera to 40 years to life for each count, to be served consecutively.

Surveillance video played at trial of the parking lot showed Rivera approaching the couple, and the three appear to argue before Rivera pulled out a handgun and fired.

In their opening statement, Rivera’s defense acknowledged he is the man seen on surveillance video gunning down Swett and Champagne in a downtown Nashua parking lot, but they urged jurors to keep an impartial mind. The defense argued Rivera never formed a criminal intent, because he was “so shocked, stunned and overwhelmed” when he found out that his friend and ex-girlfriend were dating, which enraged Rivera because he had previously accused them of being romantically involved while he was dating Swett, but they denied it.

Rivera took the stand during his trial and admitted to firing his gun a total of seven times, but said his memory was “blurry.”

  • Prosecution and Defense deliver openings
    • Victor Rivera’s public defender, Maya Dominguez, acknowledged Rivera is the man seen on surveillance video gunning down Tricia Swett and Matt Champagne in a downtown Nashua parking lot, but she urged jurors to keep an impartial mind until Rivera takes the stand.
    • Dominguez said Rivera never formed a criminal intent, because he was “so shocked, stunned and overwhelmed” when he found out that his friend and ex-girlfriend were dating. This revelation purportedly enraged Rivera because he had previously accused Swett and Champagne of being romantically involved — while Rivera and Swett were still in a relationship, and — according to Rivera — they “gaslit” him and convinced him he was mistaken. Once they had convinced Rivera there was nothing going on between them, the pair then sought an apology from Rivera for lodging the accusation, and he did so at that time.
