Someone who knew Lee Halpin has left this tribute to him on a Facebook page for a film organisation that he was associated with:
Lee Halpin has passed away during a fearless conception of a documentary he hoped would be seen by thousands of people and make an impact raising awareness about homelessness.
Sleeping rough for one week with no holds barred, he was chasing a dramatic narrative, a rebirth as a human and film that would make a difference.
With a BANG and a strong seed planted he has departed and I will do everything I can to finish this film and make the mark he hoped to leave.
