SMITH RIVER, Cal.--A Brookings family is desperate to find their family member, who hasn't been seen or heard from in almost a month.
Max Greenfield's image was captured on security video leaving a casino in Smith River March 18th.
The family conducted a search party almost two weeks ago.
Tonya Brown, Max’s sister says they covered about 10 miles across the beaches.
The sheriff’s office has also done land searches with their search and rescue team and using their cadaver dogs all around the casino.
She believes they've covered any areas he could have fallen into, which is why she thinks there may be foul play involved.
Tonya Brown says, "What we really need to know is we need someone to come forward and have either a confirmed sighting or know he is actually gone and what really happened. I just feel like if nobody has seen him since the early morning of March 18th, then what happened to him? Somebody knows, people don't just vanish."
Max was last seen on security video leaving the 'Lucky 7 Casino' around 2 a.m.
The footage shows him meeting a man the front of the casino, and after talking for a few minutes, walking south across the parking lot, near Highway 101.
Anyone with information should call the Del Norte or Curry County Sheriff's Office.
