U.S. Marine Corps veteran Robert Sundin, 70, was shot dead on Thursday morning when he came to the aid of a restaurant worker during an armed robbery in Vallejo, California. 

"He saved my life. That's the type of person he was. He saved my life. He's always going to be my guardian angel for life," said Teresa Brasher about Sundin, as reported by Fox 2.

Sundin, a married father who worked in the VA healthcare system, would arrive at Scotty's Restaurant at Tennessee and Tuolumne streets every weekday morning, at 5:30 a.m. 

Brasher noted, "God wasn't ready for me. But they had a place for Bob up there."

On that fateful Thursday morning, Brasher noticed a man in a hoodie and ski mask riding an electric scooter.

She said, "He came up to my door, and he pointed his finger at me. He was pointing at my purse. I don't know if he used his finger or a gun."

At that point, Sundin, a Scotty's regular, exited his vehicle. 

Brasher continued, "The guy grabs him. And I can see Bob pulling away like that, and that's when I heard the gunshot go off."

Sundin was dead at the scene as the shooter fled.

Brasher added, "He's my hero. He'll always be my hero for life."

According to Fox 2, Sundin would sit in the same seat every morning, reading the newspaper and making small talk, while restaurant staff would cook up his regular order.

Scotty's owner, Nay Ung, said of Sundin, "That's what makes it hard. He was just such a wonderful man. It was just somebody you come across, and you feel comfortable talking to him."

Sundin was a volunteer at First Assembly of God, a Fairfield church. 

Pastor Eric Lura said, "If there was a need he saw at the church, he met it. He was the first person to arrive and last to leave."

Democratic Rep. Alexandria Ocasio-Cortez has joined the chorus of those criticizing Twitter chief Elon Musk after he suspended several liberal journalists from his social media platform Thursday.

In a pair of tweets, Ocasio-Cortez, D-New York, accused Musk of "abuse of power" and encouraged him to "lay off the proto-fascism" hours after he temporarily barred journalists who worked for CNN, the New York Times, the Washington Post and others.

Musk claimed the journalists allegedly violated the platform’s new policy not to share real-time location information when they posted "assassination coordinates."

"Take a beat and lay off the proto-fascism. Maybe try putting down your phone," she wrote, sharing one of Musk’s tweets.

ELON MUSK POLLS USERS ON REINSTATING SUSPENDED JOURNALISTS, DEFENDS HIMSELF IN TWITTER SPACES CHAT

Musk spent several hours Thursday evening defending his decision to suspend the journalists, through several tweets and participation in a Twitter Spaces conference call.

"They posted my exact real-time location, basically assassination coordinates, in (obvious) direct violation of Twitter terms of service," Musk wrote Thursday.

"Accounts engaged in doxxing receive a temporary 7 day suspension," he continued.

And, "Criticizing me all day long is totally fine, but doxxing my real-time location and endangering my family is not."

The Democratic lawmaker suggested Musk should not have suspended them as he is a "public figure" who, like her, is sometimes the victim of such location or personal information-sharing behavior.

"You’re a public figure. An extremely controversial and powerful one. I get feeling unsafe, but descending into abuse of power + erratically banning journalists only increases the intensity around you," Ocasio-Cortez wrote.

The New Yorker added: "As someone who has been subject to real + dangerous plots, I do get it. I didn’t have security and have experienced many scary incidents."

"In fact, many of the right-wing outlets you now elevate published photos of my home, car, etc. At a certain point you gotta disconnect," she suggested.

Musk brushed the criticism, simply responding: "You first."

Earlier in the day, Musk banned journalists including CNN correspondent Donie O'Sullivan, New York Times technology reporter Ryan Mac, Washington Post reporter Drew Harwell, The Intercept journalist Micah Lee, Mashable writer Matt Binder, former MSNBC host Keith Olbermann and former Vox journalist Aaron Rupar.

He said the suspension would be lifted after seven days, but seemed to change his mind hours later as he polled his followers, asking them what course of action should be taken.

Musk has not yet said if he would honor the results of the poll, which is favoring the reinstatement of the journalists
