Marin was very forthcoming when confessing to the murder and it was Marin’s information that led police to Crockett’s body. Police note that the motive is not exactly clear. However, Crockett’s brother Jesse told police that Marin was a “heavy drug user” and that he was also a “religious zealot.”

It appears that Isaiah’s brother, Samuel Marin, may have expressed the likely motive when he told police about the murder. Samuel said that he and Isaiah were playing a card game and the victim was in the room with them. Samuel stated Isaiah had been watching YouTube videos related to his Christian beliefs and during the card game, Isaiah picked up a large black sword and began swinging it. Samuel stated he heard a noise “described as the sound of someone getting stabbed. He stated he looked up and saw Jacob stand up and blood gushing from his chest.” Samuel told police that Isaiah was still holding the knife.

Scared, Samuel ran from the apartment. He said his brother followed him attempting to calm him down.

” [He said he] would explain why he killed Jacob from letters he would write while he was in prison.”
