Ron Dumper died in a building collapse in 2019. This is known.
As for the current imposter (3rd?) they are Hilarious Clit, a politics woman, wearing a fatsuit and makeup. It is known that women can imitate men better than other men and 'the Hil' was the only person so dedicated and so desperate to play the role that they could do it. Like Tarantino said, "without [the Hil], this [operation] couldn't be made".
