David was a famous Vinewood film producer. In 1929, he founded Richards Majestic Productions, which he ran until 1978, when his son Solomon took over the business. According to the WhokilledLeonoraJohnson.com website, David was well-known in the industry for his good heart and generosity, though Solomon refers to his father as a "delusional man". In Peter Dreyfuss' confession letter, it is implied that David's wife was called Rachel.
David was a close friend of Peter Dreyfuss, although how they met is unknown. During one night in Mexico, Richards and an inebriated Dreyfuss paid two prostitutes to stab each other to death. In 1975, when Dreyfuss murdered actress Leonora Johnson, he wrote a letter to David confessing to the murder. David destroyed the letter, but ended up confessing the existence of it to his grandson, Ira Richards, before he died.
