Gilles Delisle

The Delisle triple murder was the April 2010 gun slaying of Gilles L. Delisle (69) and his wife Helga Harries Delisle (72) and their business partner Peter J. Weith (68), at the Delisle home on Mesilla Hills Drive outside of Mesilla, near Las Cruces, New Mexico. A $10,000 reward was offered for information leading to the shooter.

Eugene "Gino" Ferri (48 in 2011) was arrested a year later, after the murder weapon was recovered from a latrine, following a tip from Ricky Huckabay, who had driven Ferri to the Delisle's home on the day of the murders. Ferri was found guilty of the murders in May 2013, and sentenced to three consecutive life sentences.

Ferri had built the Delisle's home in 2003. He and the three he murdered had been involved in a civil dispute before the triple murder. Ferri and his mother Carol Ferri owed the victims about $1.3 million. Weith's widow took over trying to recoup the debt from them after her husband was killed in "the worst murder in Las Cruces in 20 years".

Gilles Delisle was an inventor and businessman; he had received a heart transplant in 1996, from an 18-year-old Artesia, New Mexico girl. He was well liked by many, but told friends he was in fear for his life; several of his business partners had died mysteriously.

Helga Delisle was a professor of linguistics, former head of the Department of Linguistics at New Mexico State University.

Peter Weith was the founder of the US operation of the Hegla Glass Company in 1995.
