Beaming on his wedding day, this is Salvador Sanchez, the off-duty LAPD patrol officer who shot and killed unarmed mentally disabled Kenneth French and critically-wounded French's parents at Costco.

DailyMail.com can also reveal that the French family fear Kenneth's comatose mother Paola French, who tried to protect her son from the hail of bullets, may not survive.

Sanchez, an officer for seven years, killed Kenneth French, 32, at Costco Wholesale in Corona, southeast of Los Angeles, on June 14, after French hit Sanchez.

Also present during the shooting was Salvador's wife, Rosemary Quintero and their 18-month-old son.

Sanchez had been holding the child, waiting for a food sample of chicken teriyaki at the meat counter, when his lawyer David Winslow said an unprovoked French knocked Sanchez temporarily unconscious.

CCTV footage from the store has not been released yet but witnesses claim, when he came to, Sanchez got up from the floor and fired up to eight times at French with a handgun.

Kenneth's father Russell, 58, and mom Paola attempted to protect their son from Sanchez when the officer fired, witnesses have told French family lawyer Dale Galipo.

In an exclusive interview with DailyMail.com, Galipo revealed Paola, a business analyst for California's Riverside County, is now comatose and the family fear she may not survive.

Galipo said: 'Paolo has had several surgeries since being shot and is currently in a coma, she is battling for her life, we don't know if she's going to make it.'

Russell, a financial planning analysis manager at solar panel manufacturer SolarMax, sustained less serious injuries.

Galipo could not explain why Kenneth hit Sanchez but said he was 'nonverbal' because of his mental disability and had recently stopped taking medication which had controlled his mood.

DailyMail.com spoke to friends of the French family who said Kenneth had only developed mental issues in the last 10 years, was a star pupil and attended college in Canada.

Civil Rights attorney Dale Galipo (pictured) believes LAPD officer Salvador Sanchez should be prosecuted, saying the shooting of the French family was excessive and completely unjustified

Russell, who was born in Calcutta, India, had studied accountancy in London and Kuwait before moving to Mississauga, near Toronto, Canada in 1978.

He married Paola in 1986 and Kenneth was born a year later. Their son proved to be a gifted student at school before he developed a mental disability a decade ago.

Family friend Naiera Fulgado of Mississauga, told DailyMail.com: 'They are the kindest and most-loving people I've met.

'Kenneth was in the gifted program growing up and even attended McMaster University in Hamilton, Ontario but something changed about 10 years ago.'

It is believed his mental disability reduced his mind to that of a 10-year-old.

Kenneth, who Galipo said had no history of violence, moved to the United States with his parents in 2013 and lived with them at their $700,000 five-bedroom home in Riverside, California.

Galipo said: 'Kenneth had been taken off his medication due to his health complications which may have affected his behavior.

'I haven't seen any video tape of the incident as of yet but I'm hearing the police officer fired his pistol as many as seven or eight times.

'From my understanding Russell French attempted to get between his son, Kenneth and the police officer and that is how he ended up getting shot.

'I also believe that the mother Paola was possibly behind them and took one of the bullets. We are still waiting for the Corona Police Department to finish their investigation.'

Galipo added the shooting wasn't a life-threatening situation for the police officer and has called for the criminal prosecution of the officer - saying the shooting was excessive and completely unjustified.

Los Angeles Police Department has placed Sanchez, who has been a patrol officer since May 2012, on administrative leave.

Sanchez began his career with the LAPD's Rampart Division and is now based with the Southwest Division.

He married Rosemary Quintero, 30, in a cliff side ceremony at Rancho Palos Verdes, close to Long Beach, California, on July 9, 2016.

The service, with Catalina Island and the Pacific Ocean in the background, was officiated by LAPD chaplain Glenn McConnell.

Describing the event for the LAPD union magazine Thin Blue Line, McConnell wrote: 'May Sal and Rosie share a lifetime of joy and happiness as they begin their life together.'

As well as work as a patrol officer, Sanchez had set up a police clothing business in 2015 with Rosemary, Slide Lock Uniforms, based in the back apartment of a house they rented in Torrance, California.

Their company advert stated: 'We make custom made law enforcement uniforms that are tailored to your size. Our police uniforms are made with quality fabric and made according to your likes on the job.'

The business closed in June 2017, and the couple, who then became parents, moved out in November 2018.

They have now bought a $400,000 four-bedroom home in Riverside, a short drive from the French family.

Sanchez's lawyer David Winslow maintains his client had no option but to use deadly force at Costco.

He told DailyMail.com: 'The officer was off duty and shopping in Costco with his wife and 1½ year old son.

'He was holding his son in his arms while feeding him. Without warning or provocation, he was violently attacked from behind.

'There were no words exchanged and there was no argument. He and his son were both knocked to the ground. The officer was knocked unconscious momentarily.

'While lying injured on the Costco floor, he was unprotected and had no other option to defend himself and his son from further deadly attack. He was in fear for his son's life. The only option was deadly force.

'The entire situation is a tragedy for all concerned.'

Corona Police Chief George Johnstone said they are still interviewing witnesses and evaluating video and forensic evidence from the store.

He told reporters: 'For several reasons, including the need to interview a number of witnesses and review evidence, no arrest was made at the time of the incident.

He added: 'Once all the evidence has been gathered and evaluated, it will be presented to the Riverside County district attorney for a decision on charges.'

Kenneth's cousin Rick Shureih hopes CCTV footage at Costco will show what happened.

He posted on Facebook: 'City of Corona Police Department my family has faith that you will do the right thing and arrest the gunman!

'Our family has witness accounts that do not match up to the original story. We are a pro police family.

I have many friends in Law Enforcement. We need justice to prevail! Please review the surveillance tape!'
