Darrell Sheets’ girlfriend shared heart-wrenching details about the “Storage Wars” star’s final moments in her 911 call.

After the reality star’s partner, whose name is not known, “heard a gun go off,” she dialed the emergency dispatch service and said, “I think he just killed himself. Yeah. Darrell.”

In the audio, obtained by TMZ on Thursday, noted that she had not “see[n] anything” because she “did not want to look.”

Sheets’ girlfriend added that before the 67-year-old’s self-inflicted gunshot wound, he had “just yelled at [her].”

She explained, “I was up. I was like, ‘What are you doing?’”

Later in the call, she clarified that she was “out in the garage” while Sheets was in the office.

Sheets’ girlfriend was audibly shocked throughout the conversation, requesting the operator “hold on” multiple times and taking deep breaths.

“I can’t believe it,” she said, before clarifying the storage locker buyer had been battling insomnia in his final days.

“I know he’s been just frustrated with this no sleep and his kids,” she told the operator. “Terrible, terrible.”

Sheets was “pronounced deceased on scene,” the Lake Havasu City Police Department revealed after his passing.

Page Six obtained a police incident report on Wednesday and broke the news that Sheets left behind a suicide note.

It referenced “Facebook bullying” he “couldn’t take” anymore.

His girlfriend told officers that Sheets got out of bed late after being unable to sleep, and he told her to “go back to bed” when she went to the doorway to his office — after which she “heard a single gunshot.”

The report mentioned Sheets’ chronic “sleep deprivation,” as well as details from the girlfriend about his recent “family drama.”

Sheets’ autopsy report confirmed he died by suicide, with his toxicology analysis coming back negative.
