Dona Ana County prosecutors say 52-year-old Carlos Garcia was sentenced Monday in Third Judicial District Court.
Garcia originally was charged with two counts of first-degree murder in the May 2017 deaths of 29-year-old Denise Chavez and 36-year-old Arturo Cordova following a party in Las Cruces.
Authorities say Garcia was injured in the crash and spent a month in the hospital.
Prosecutors say Garcia pleaded guilty last month to two counts of second-degree murder and one count of aggravated assault with a deadly weapon.
