Federal OSHA has now fined Disney $6,300 for Cruz's death.
Marin, his sister, said someone who worked with her brother told her that he tripped in front of the float and there wasn't enough time for him to move.
'It's not acceptable'
"We believe it could have been prevented. I believe they should have kept a distance between him as a character and the float," she said.
"OK, it's an accident, but it's not acceptable. They should have prevented this."
