Once the family was out of the house, the officers confronted an armed Chavez, who was hiding inside. That's when the shooting began leaving Walsh, who was first through the door, injured and Chavez dead.

"Any police officer can have an encounter suddenly turn violent," Joseph said in a statement. "Our MERGE Officers, by contrast, are called primarily because violence has already occurred or is highly likely, and it takes an extraordinary person to willingly face that level of danger again and again. I am grateful for Sergeant Matt Walsh and his team for their dedication to protecting those who need them, even in the most volatile situations imaginable."

Walsh, who MERGE Unit's supervisor, has been with the department for 19 years.

“The City will support Sergeant Walsh through his recovery and stand with him and his family, loved ones and colleagues during this difficult time,” City Manager Jennifer Maguire said in a statement. “An officer-involved shooting is a serious and deeply impactful event, and its effects are felt throughout the organization—by the officers who responded, the dispatchers who heard the incident unfold, and all City employees who serve our community. I am grateful for the courage and commitment of the officers who put themselves in harm’s way to protect our residents. We should never take their sacrifice for granted.”

This San Jose's second officer-invovled shooting this year. It remains under investigation.
