Colton praised Jon’s ability to ‘speak volumes with just a look’ as he shared photos of his late co-star. 

“John Miyahara, known as Brett from Superstore, has unfortunately left us. John was an amazing person and could convey so much emotion with just a glance,” Colton, who portrayed Garrett, expressed in a post on Wednesday.

“He was an unforgettable member of the Cloud 9 family. It was a privilege to know and work alongside him. I had the fortune to meet some of his loved ones and my heart goes out to them. Rest in Peace, John.”

In the comments, various members of the Superstore family sent their condolences.

‘Oh man! He was always so sweet! Rest in peace,’ Castmember Kelly Stables, who played Kelly, posted.

‘Oh no, he was literally the sweetest man. Prayers up to his family and loved ones,’ Superstore writer and producer Sierra Teller Ornelas wrote.

‘What an incredible man,’ co-star Irene White wrote.

One Walmart manager described how the show, which followed the adventures of employees working at the big box store Cloud 9, touched his life. 

‘Rest in peace,’ he commented on Colton’s post. ‘I am currently a manager for Walmart and this show literally shows what it is to work retail and how hard working people try to survive with retail salaries and I truly love the beauty of this show. Laugh, love, and passion for the work. Thank you all of you for showing the good side of it!’

One fan described how much the show touched their lives as they sent their condolences 

‘Background actors work very long hours and get little recognition or compensation. But as you can see from the response, he made a mark in his performance [as] Brett,’ he told the outlet.

The outlet reports that paramedics were at Jon’s home in Los Angeles just over a week ago. 

An EMS call was placed for an elderly man who had fallen and was in pain, law enforcement sources told the site. The call was reportedly made at 7:15 on July 28.  

He was taken to a local hospital ‘awake and breathing’, police said. The website adds it is not known if he passed at the hospital or at his home.
