<P> In October 2012, A&E Network and the History Channel, along with Harrison and the rest of the show's cast, were sued in Clark County District Court in Las Vegas for interference with business practices by Wayne F. Jefferies, a Las Vegas promoter and the Harrisons' manager, who represented them and "Chumlee" Russell in their television business dealings . Jefferies, who managed and operated the Las Vegas world cuisine restaurant Seven in 2001, and who, as an event promoter, put up to $75,000 in support of the 2005 and 2006 Las Vegas Red, White and Boom Independence Day event, was instrumental in helping to launch the series . Jefferies stated that after the show premiered, his influence in the show was increasingly reduced, and that he was ultimately fired and left without his promised share of fees and merchandising royalties from the series, purportedly due to network executives after a January 2012 report on TMZ that indicated that the Pawn Stars cast were taken aback by the History Channel's launch of the spinoff Cajun Pawn Stars, of which the cast had been unaware . </P> <P> Harrison was particularly passionate about automobiles, showing an interest in all types of cars . Cars he owned or expressed an interest in on the television series include his 1966 Imperial Crown, which took him fifteen years to convince the previous owner to sell, and was subsequently restored by his son and grandson for his 50th wedding anniversary; a 1957 Chevy 150 sedan given to him by the stars of two other History shows, American Restoration and American Pickers; and the mid-1960s B&Z Electra - King electric car shown to them in Pawn Stars season 3 episode 14 ("Honest Abe"), which he suggested could be converted into a golf cart . </P> <P> Harrison died on June 25, 2018, after a battle with Parkinson's disease . His funeral was held July 1, with his casket draped in an American flag on account of his service in the Navy . His son Rick eulogized him thus: "He was my hero and I was fortunate to get a very cool' Old Man' as my dad . That I got to share him with so many others and they got to see what a great family man he was is something I am grateful to have experienced with him ." Harrison was survived by wife JoAnne, three sons, 10 grandchildren and five great - grandchildren . Harrison placed his son Rick in charge of his estate . Christopher Harrison, the youngest of Harrison's three sons, was intentionally omitted from his father's will . </P>
