Eric Heard was sentenced to 75 years to life in a Fresno County courtroom on Thursday.
Police say he shot 33-year-old Fanchon Moore and 17-year-old Antonio Rodriguez after an argument in October of 2021.
It happened at a home on Weathermaker and Winery Avenues in east central Fresno.
Heard was originally arrested on a previous misdemeanor warrant, before being charged with the murders.
He changed his plea to guilty in this case during a hearing last month.
