Javier Martin seems like a real piece of work. While he is being tried in print, the evidence against him is overwhelming.
He worked for the Frenchman, then moved that Catamaran
to another port and presented paperwork showing he had bought it. Was changing the name and appearance of the boat when the Frenchman's body was discovered.
He was known to have left with Don North on his boat, which turned up later with another name on it.
He was in possession of Don North's credit card when apprehended, as well as a pistol which is likely the weapon used to murder the Frenchman.
He left lots of stuff of Don's boat stashed in a tent, including Don's gun.
He made a number of threats along the lines of 'I'll kill you if you go to the police, and I've killed before'.
The latest is that the paperwork for the boat he came on and wrecked on a reef (left port in a bad storm) looks like a forgery, and now they are chasing its history
to see if there was yet another cruiser that disappeared.
