On June 8, 2024, deputies performed a welfare check at a home on East Mettler Road near Lodi after family members could not reach the occupants for over a week. Inside, they found three people shot to death: 69-year-old Kim Huynh, 60-year-old Joe Pena, and their 45-year-old son, Alfred Nguyen.

Investigators concluded the killings appeared targeted and carried out by someone familiar with the family. To avoid compromising the case, officials initially withheld details. On September 14, 2024, authorities arrested 25-year-old Steven Guerrero Jr. of Stockton and charged him with three counts of murder, burglary, and firearm enhancements; prosecutors described the crime as targeted, calculated, and vicious and said the death penalty was being considered. Guerrero was arraigned on September 17, 2024, and remained in custody without bail as of December 2024.

The exact relationship between Guerrero and the victims and the motive for the attack have not been publicly disclosed. Does anyone have information about the family or their connections in the Lodi and Stockton area that could help investigators?
