A 50-year-old man goes on trial Monday in Las Cruces in the 2010 killings of a New Mexico couple and their business partner from California.
First-degree murder charges accuse Eugene Ferri of fatally shooting 69-year-old Gilles Delisle, 72-year-old Helga Harries Delisle and 68-year-old Peter J. Weith of San Diego.
Ferri had worked for the Delisles as a contractor, and they and Weith had sued Ferri for $1.3 milion.
The victims' bodies were discovered at the Delisles' Mesillas home after they didn't go to a court hearing.
A driver for Ferri led police to the homicide weapon, a gun hidden in a toilet at a Las Cruces park.
Defense attorney Gary Mitchell says his client has an alibi and documentation to prove he was elsewhere.
