More than a month after the body of Nolan Wells was found along the shoreline of a Mississippi barrier island, three friends believed to have traveled out to Horn Island with Wells will return there in an effort to investigate the case, their attorneys tell CNN.

Warren Hudson, Jax Pitalo, and Morgan Seymour, who are believed to have been with Wells on the Fourth of July, the day he went missing will go to the island to “investigate the layout and dynamic,” their attorneys, Edward Andrew Paltzik and J. Tyler Cox, told CNN. It is unclear how the group intends to handle its unofficial investigation on the island.

It’s also unclear if Hudson, Pitalo and Seymour were with Wells that day, or if they have been interviewed by police, but in July Jackson County Sheriff John Ledbetter, told the Sun Herald that three friends who traveled with Wells on the boat to Horn Island had been interviewed in depth.

“We are proud to stand with and fight for three completely innocent young men,” the attorneys said in a joint statement.

“We…will be focused solely on the truth, which is that these innocent young men had nothing whatsoever to do with the tragic death of Nolan Wells.”
