An ailing Vietnam veteran who was in the care of a top Veterans Affairs Center in Massachusetts was left to die — as his caregiver played video games on her computer, according to a disturbing report.

Bill Nutter, who was exposed to the toxic herbicide Agent Orange in the 1960s, was supposed to undergo hourly checks while at the Bedford VA Medical Center, the Boston Globe reported.

The sickly 68-year-old suffered from arrhythmia – which could cause his heart to stop at any moment – had respiratory problems, couldn’t get out of bed on his own and had just lost his second leg to diabetes.

He died July 3, 2016 after going into cardiac arrest, which the hospital insisted “[they] couldn’t do anything about it,” his wife Carol Nutter was initially told.

But a few days later, the grieving widow got a phone call from a doctor, who was repeating what a woman in the

background was telling him.

The woman was saying, “They weren’t doing their job, and if they had done what I told them to, he could have possibly been alive because I told them to check on him once or twice an hour.”

An investigation by the VA Inspector General eventually revealed that Patricia Waible, the nurse’s aide assigned to regularly check on Bill Nutter that evening, was playing video games on her computer — rather than doing her job.

At first, Waible lied, saying she made the required checks on Bill Nutter and had initialed corresponding paperwork. But she confessed after an investigator told her the hospital’s cameras showed she never moved from her computer during her shift.

Waible was reassigned pending the investigation.

Meanwhile, the nurse who found Nutter unresponsive the next morning crudely indicated to her supervisor that he was dead by sliding her finger across her throat, according to internal hospital records. She was terminated.

“Poor Bill, I fought to keep him alive,” said Carol Nutter. “We were married for 47 years. I was always with him. He wanted me there. But I wasn’t able to watch over him at the end.”

Now, Bill Nutter’s family is weighing their legal options.

“My dad might not have lived another five months, who knows? But if we could have had another month with him — this lady took that away,” said his daughter Brigitte Darton.
