Valadez was arrested in Mexico and extradited to the United States less than two weeks after the deadly shootings.
Around the time of his arrest, prosecutors said the killings were intended to cover up sexual crimes he committed days earlier.
The San Diego County District Attorney's Office said then in a statement that the murders stemmed from a confrontation "in which (Valadez) was trying to silence family members who were potential witnesses" to an alleged sexual assault of an 18-year-old family member that occurred two days prior.
Valadez was also charged with felony sexual assault for the alleged abuse of his family member. Those charges were dismissed as part of his plea to the murder counts.
Valadez also admitted a special circumstance allegation of committing multiple murders, which can trigger a sentence of life in prison without the possibility of parole. Sentencing is scheduled for Nov. 15.
