Lake Havasu City police found the "Storage Wars" star dead on 22 April from an apparent self-inflicted gunshot wound, and his son Brandon later posted an emotional tribute.
Police said the death remains under active investigation, including allegations of cyberbullying raised by co-stars Laura Dotson and Rene Nezhoda, who said Sheets had felt targeted for years.
Sheets, nicknamed "The Gambler," appeared in more than 160 episodes of the A&E reality series after it began in 2010, becoming one of its best-known buyers.
