“We lost one of our beautiful Associates tonight. She was taking care of our most important asset – our customers, and her life was taken by a disgusting human who doesn’t value the lives of others or his own.

“He shot both on our property and off, and ended his life shortly after he took the precious lives of our Associate and Customers, innocent people who never saw it coming.”

The only victim to be identified thus far is Terry Dudley.

The company that he works for, North Star Taxi, said he has “a very long road ahead of him.”

Terry was charging his Tesla when he was shot in the back twice, according to a GoFundMe page.

A statement on the fundraiser read: “Our community experienced the kind of tragedy that changes lives forever.

“A senseless act of violence took the lives of innocent people, left many others critically injured, and shattered countless families in an instant.

“Our hearts are with every victim and every loved one who is now facing unimaginable grief and uncertainty.

“In a matter of moments, an ordinary day became a nightmare that no family should ever have to endure.”

The page, which was set up to help “tenacious, compassionate, kind hearted” Terry, has raised more than $8,000 so far.

Police found Williams’ body in an area near the restaurant.

Bullets began ringing out at around 3pm local time, with shocking footage showing dozens of people fleeing for their lives.

Williams drove up to the chain’s drive-thru before exiting a white vehicle and retrieving a rifle from the trunk.

Wearing a black T-shirt and blue trousers, he was seen walking through the car park before shooting through a Tesla‘s windscreen.

Someone in an In-N-Out uniform was later filmed dragging a person, also uniformed, bleeding from a gunshot wound in her chest across the parking lot.

Twin Falls resident Haley Dodaro, 43, was having lunch in In-N-Out with her mum when she saw people running across the street.

“People were running out crying and screaming”, she said.

Officials were still working on notifying the family members of victims.

Apart from Terry, names, ages and other details of those wounded in the shooting have not been released.

The FBI confirmed it would be assisting in the ongoing investigation.
