The image was originally uploaded Friday to the Facebook page of Caitlin Cimeno, pictured in the middle, with the caption "Happy Halloween from Zimmerman & trayvon." It was tweeted on Sunday by @jamievandekamp.

The man dressed as Martin is William Filene, 25, of Cape Coral, Florida, the Smoking Gun reports.

22-year-old Greg Cimeno, also of Cape Coral, is dressed as George Zimmerman. He allegedly commented "anything for the laugh," after Cimeno posted the photograph to Facebook on Friday.
