"Legal Purchase, Schizophrenic Suspect: LA Deputy's Ambush Killing Investigation Unfolds"

The gun used in the ambush killing of a Los Angeles County sheriff's deputy appears to have been legally purchased, raising questions about the suspect's mental health background. Investigators are looking into whether the suspect had a documented history of psychiatric problems that should have raised red flags during the gun purchase process. The motive for the shooting remains unclear. The suspect has been arrested and reportedly confessed to the crime. The deputy, Ryan Clinkunbroomer, was described as a dedicated and hard-working officer who made the ultimate sacrifice.
