Donna Fairchild and Bill Fairchild were found in a residence in the city of Mesquite, Nevada, on Interstate 15 near the border with Arizona, authorities said. Police got a call from the residence about 4:30 a.m.
Each apparently suffered a single gunshot wound, the city said. Autopsies are scheduled for Wednesday.
Results from the Clark County Coroner's Office were expected to take four to six weeks, according to a statement from the city.
Mesquite city spokesman Bryan Dangerfield would not comment on the circumstances of their deaths but said police confirmed that a note and a 9 mm handgun were found at the scene.
For those keeping track - that's now 3 people of government killed and/or gunned down in the last month.
