Police in Sunnyvale have arrested two men, including the father of the victim's young son, in the January 7 killing of 24-year-old Kembery Chirinos-Flores. The shooting occurred at a mobile home park, and Chirinos-Flores was found fatally shot in her car, which was not at her residence in Mountain View.

Why it matters

The arrests in this tragic case of domestic violence provide some closure for the victim's family, though the loss of a young mother is deeply felt in the community. The prior domestic violence history of one suspect also raises questions about bail reform and whether more could have been done to prevent this violence.

The details

Gerzon Chirinos of Sunnyvale, also known as Gerzon Chirinos-Munguia, who is the father of Chirinos-Flores's 5-year-old son, was arrested along with Alfonso Inestroza, aka Franquin Inestroza-Martinez, of Hollister. Chirinos had a previous domestic violence arrest on his record from 2018 involving another partner. Inestroza reportedly had a warrant out for his arrest in New Jersey on an unrelated murder case.

  • The shooting happened on the night of January 7 at the Plaza Del Rey mobile home park in Sunnyvale.
