Thomas Ulibarri, 58, a lifelong resident of Santa Rosa known for his faith and willingness to help others, was shot and killed at his North 8th Street home on the afternoon of September 20, 2021. According to reports, a dispute involving Ulibarri, his wife, and his 44-year-old stepson, Rex Saiz, escalated around 2:30 p.m. Saiz allegedly produced a firearm, fired at his mother and missed, then shot Ulibarri. Ulibarri was pronounced dead at the scene by the Office of the Medical Investigator.

After the shooting, Saiz fled but was located the same night at a Super 8 Motel in Santa Rosa and taken into custody without incident; the motel room also contained his 50-year-old girlfriend, Gina Tower. Saiz was charged with an open count of Murder in the First Degree and Attempted Murder in the First Degree, and Tower was charged with Harboring or Aiding a Felon. Does anyone in Santa Rosa have information about the dispute or the people involved that could shed light on what led to this killing?
