Fa’anunu who was sentenced on Wednesday will also spend 36 months in prison for a misdemeanor child endangerment.
That includes six months for every child present in the home at the time their mother was killed.
“By committing such a cruel and violent act, he has broken the hearts and lives of hundreds of people including his own children,” said Sara Wright, Mary’s sister, according to San Diego 7 news.
Mary Fa’anunu was 34 when she died in the family’s home on Melrose Lane in unincorporated El Cajon.
