Jose Garza aka Christopher Harlow was a drug trafficker and murderer on the run from the FBI. At some unknown point he killed a man named Ben "Spider" Koff and has since then been a fugitive on the run from the FBI. Garza purchased cocaine from Santos Jimenez, but never got it because Jimenez was killed by Dexter. Garza came looking for him, sending various text messages to Jimenez's phone, which was now in Dexter's possession. Garza had no idea that he was really talking to Dexter and also didn't have knowledge about Jimenez's cabin in the Everglades at first, but he eventually found it out and threatened to go there. Dexter, however, had locked Doakes in the cabin and did not want to risk Garza discovering his secret.
