Anton Yelchin's parents bought a touching full page ad in The Hollywood Reporter to thank the fans for their support and kind words after their son passed away last month. Yelchin was killed when his car slipped out of gear and accidentally pinned him to a pillar and he asphyxiated to death. Irina and Viktor Yelchin published a black and white photo of their son with a message to fans that read, "?To all of you who have sent flowers and gifts, for your condolences and kind words and to all who came to celebrate the life our? son, Anton. We are deeply grateful for your unconditional love ? He would be surprised at how many hearts and souls he touched. Thank you very much, Irina & Viktor Yelchin.?
