A fatal shooting that claimed the lives of two Palm Springs police officers nearly one year ago began with the most cliché of trivial arguments – two siblings fighting over a television remote.

John Hernandez Felix, a man with a violent history, began arguing with his sister over the remote, prompting his mother to call police, according to new accounts of the shooting revealed by a psychologist and confirmed by prosecutors. Minutes later, when cops arrived on his doorstep, Felix opened fire with an assault rifle.

Until now, it has never been revealed what sparked the domestic incident that brought police to Felix’s house in the first place. The argument over the TV remote was recently disclosed during a courtroom exchange between Assistant District Attorney Michelle Paradise and Hilda Chalgujian, a psychologist who evaluated Felix. The details were later confirmed by the Riverside County District Attorney’s Office.

Chalgujian's testimony calls into question if the shooting was a pre-planned attack by Felix, as law enforcement officers have alleged, but confirms that Felix expressed a deep-seated hatred of police officers, who he said were “picking on” him and his family. Felix admitted to obtaining an AR-15 and a bullet-proof vest, Chalgujian said, and he mentioned recent shootings that target police officers.

“My impression is that he was getting ready to protect himself,” Chalgujian said in court. “He was certainly gearing up for ..."

“A battle with cops?” Paradise interjected.

“Armageddon,” the psychologist answered.

Felix, 27, of Palm Springs, is currently facing the death penalty for the murder of officers Jose "Gil" Vega and Lesley Zerebny, both of whom were fatally shot on his doorstep on Oct. 8, 2016.

Police have said the officers were responding to a 911 call about a domestic disturbance, then encountered Felix at the front door, where he threatened to shoot them. Felix allegedly opened fire through the door, fatally shooting Vega and Zerebny and wounding a third officer. Felix then hid in his house for a 12-hour standoff, which finally ended when police forced him outside with flashbangs.

District Attorney Mike Hestrin later described the shooting as an "ambush" and said the slain officers had "walked into a trap."

Felix, a known gang member and previously convicted felon, also faces additional felony charges for alleged use of an assault weapon, body armor and armor-piercing bullets.

However, John Hall, a spokesman for the DA’s Office, recently confirmed that prosecutors will soon move to dismiss the armor-piercing bullet charges because ballistic evidence suggests the bullets used by Felix were not actually armor-piercing.

Felix, who has pleaded not guilty to all charges, has claimed to three psychologists that he cannot remember the shooting because he suffers from “traumatic amnesia,” a loss of memory that is more common among crime victims than perpetrators.

Defense attorneys argued last week that Felix was incompetent to stand trial because he could not help his attorneys with his defense if he could not remember the shooting. Two of the psychologists said it was difficult to know if the amnesia claim was genuine, but even if it was, they felt Felix was competent to stand trial.

The third psychologist, Chalgujian, said Felix “certainly” had amnesia and was not competent to stand trial. However, Chalgujian’s credibility came under question in court after it was revealed she worked as a law clerk for Felix’s defense attorney, John Patrick Dolan.

Chalgujian testified that Felix said he remembered the argument with his sister over the television remote, then he remembered the sound of flashbangs and a police robot breaking into his home as he was captured. Everything in between was a blank.

“There is a gap where he could not remember, and I asked multiple times in different contexts, and he just could not remember,” Chalgujian said.

Despite this amnesia claim, Riverside County Judge Anthony Villalobos ruled Felix competent to stand trial last Thursday. He is scheduled to return to court for a preliminary hearing, which will lay out evidence in the case, on Dec. 15.
