John Kristensen, 34, of Fallbrook, California, was found fatally shot inside a house in the 4300 block of Rainbow Vista Drive near Old Highway 395 on April 4, 2022. Deputies with the San Diego County Sheriff’s Department discovered his body at about 7:45 a.m., and homicide detectives opened a criminal investigation into the shooting.

Investigators quickly identified 30-year-old Brian Bass of Carlsbad as the primary suspect; Bass and Kristensen were known to be friends. On April 5, 2022, deputies served a search warrant at Bass’s home in the 3800 block of El Camino Real in Carlsbad and arrested him. He was booked into the Vista Detention Facility on suspicion of murder. Authorities said motivations and circumstances were still under investigation and no other arrests had been reported.

Does anyone have information about Kristensen or his movements in the days before April 4, 2022 that could help investigators?
