“Storage Wars” star Mary Padian mourned the loss of her former castmate Darrell Sheets after his shocking death.

“Some people become part of a chapter in your life that you never forget,” Padian, 45, wrote on her Instagram Stories Wednesday.

“You will be missed Darrell,” she added.

The former reality star shared a smiling selfie of herself, Sheets and another man at a restaurant.

Sheets’ “Storage Wars” rival, Brandi Passante, also penned an emotional tribute on social media, saying she had known him a long time and was “at a loss for words.”

“I’m just so very sorry, to hear the circumstances of his passing,” Passante, also 45, added.

As Page Six previously reported, on Wednesday, police responded to reports of a deceased person at Sheets’ home.

The Lake Havasu City Police Department in Arizona said in a press release that the A&E star died from an apparent self-inflicted gunshot wound to the head. He was 67.

“The male was pronounced deceased on scene, and the Lake Havasu City Police Department’s Criminal Investigations Unit was notified and responded to the scene to assume the investigation,” the press release read.

While it’s unclear what led to Sheets’ death, “Storage Wars” star Rene Nezhoda said in an Instagram video that he believes he was cyberbullied before he took his own life.

“He had this guy, like, really, really tormenting him lately and cyberbullying [him],” Nezhoda, 49, said.

“Darrell has been posting a lot about the guy that’s been cyberbullying him and tormenting him, and I really hope [law enforcement] look into that guy and it’s just not a pass,” he added.

“Guys, just because you watch us on television doesn’t mean you know us. It doesn’t mean you know what we’re about.”

The department’s public information officer, Sergeant Kyle Ridgway, told Page Six Wednesday that they “are aware of these cyberbullying accusations and that is a part of the active investigation.”

Sheets was last photographed walking his dog in a final Facebook photo shared on Feb. 6.
