Overview
- Firefighters responded to two separate fires on the 15th Street block on Tuesday night and found a family of four unconscious in the second home after it became a three-alarm blaze.
- Police confirmed three people have died: a 47-year-old man and two young children, and a 33-year-old woman remains hospitalized in critical condition.
- Officers arrested 32-year-old Sergio Rivera-Vega near the scene and booked him on two counts of murder and two counts of arson causing great bodily harm.
- Authorities say the two fires were started independently, a woman has been arrested in the earlier nearby blaze, and both incidents are under separate active investigations.
- Relatives say the suspect had made threats and had mental-health problems, but police have not established a motive and the criminal and fire investigations will determine cause and next steps.
