The deputy involved in the Solana Beach shooting Monday had also been involved in a shooting in Encinitas in November of last year.
Deputy Noah Zarnow, assigned to the North Coastal Station, is a five-year veteran with the San Diego County Sheriff's Department (SDSO).

Around 3:30 p.m. Monday, deputies had responded to a report of a stabbing inside a Rubio's near Highway 101.
Robin Rodriguez, 49, the manager at Rubio's had been stabbed in the head, SDSO said.
The suspect, 34-year-old Emmanuel Ibarra, took off from the restaurant. He was armed with a knife when he confronted Zarnow and another deputy near Via De La Valle and Camino Del Mar.
According to SDSO, Ibarra moved toward the other deputy with the knife in his hand. While attempting to back away from Ibarra, the deputy lost his footing and fell.
The second deputy, identified as Zarnow, yelled at Ibarra, who then charged at him. Zarnow fired his handgun and struck Ibarra.
Ibarra was taken to the hospital where he later died.
No deputies were injured in the shooting.
